+# Auslegung: 12V auf 3.3V Step-Down mit SY8120IABC
+
+Dieses Dokument beschreibt das Design eines hocheffizienten, synchronen DC/DC-Abwärtswandlers. Es ist eine moderne Alternative zu älteren Designs wie dem TPS5430.
+
+## 1. Design-Ziele
+
+* **Eingangsspannung ($V_{in}$):** 12V (Bereich 10.5V - 14V)
+* **Ausgangsspannung ($V_{out}$):** 3.3V
+* **Ausgangsstrom ($I_{out}$):** Ausgelegt für ca. 0.5A, mit Reserven bis 2A.
+* **Kernbaustein:** Silergy SY8120IABC (Synchron, 1MHz, bis 18V, 2A)
+* **Ziele:** Hohe Effizienz, kompaktes Layout, minimale Anzahl externer Bauteile (keine externe Diode).
+
+## 2. Auslegung der Bauteile
+
+Die Berechnung der externen Komponenten basiert auf dem [Datenblatt des SY8120IABC](doc/SY8120I.pdf).
+
+![Schema SY8120I](SY8129I_Schematics.svg Schema der Schaltung zur Berechnung)
+
+### a) Feedback-Widerstände (R1, R2) - Optimiert für "Basic Parts"
+
+Um gängige und kostengünstige "Basic Parts" von JLCPCB zu verwenden, werden Widerstände aus der E24-Reihe gewählt. Das Ziel ist, das für ca. 3.3V benötigte Spannungsverhältnis möglichst genau zu treffen.
+
+Die Referenzspannung ($V_{FB}$) des SY8120IABC beträgt **0.6V**.
+
+Eine exzellente Kombination, die als "Basic Part" verfügbar ist, lautet:
+* **`R1` (oberer Widerstand) = 120 kΩ**
+* **`R2` (unterer Widerstand) = 27 kΩ**
+
+Die resultierende Ausgangsspannung berechnet sich damit wie folgt:
+$V_{out} = 0.6V \times (1 + \frac{R1}{R2}) = 0.6V \times (1 + \frac{120kΩ}{27kΩ}) \approx \mathbf{3.27V}$
+
+Diese Ausgangsspannung ist ideal und für alle Zielkomponenten absolut sicher.
+
+### b) Induktivität (L1)
+
+Durch die hohe Schaltfrequenz von 1 MHz kann eine physisch kleine Spule mit geringerer Induktivität verwendet werden. Das Datenblatt empfiehlt Werte im Bereich von 2.2µH bis 10µH.
+
+* Wir wählen einen Wert von **`L1 = 4.7 µH`**.
+* **Wichtig:** Der Sättigungsstrom ($I_{sat}$) muss über der Strombegrenzung des ICs liegen (ca. 3A). Eine Spule mit **$I_{sat} > 3A$** wird gewählt.
+
+### c) Kondensatoren (C1, C2, C3)
+
+* **Eingangskondensator (C1):** Ein **`10µF / 25V`** Keramikkondensator (0805) ist ausreichend, um die Eingangsspannung zu stabilisieren.
+* **Ausgangskondensator (C2):** Ein **`22µF / 10V`** Keramikkondensator (0805) wird für eine stabile Ausgangsspannung mit geringem Ripple empfohlen.
+* **Bootstrap-Kondensator (C3):** Wie im Datenblatt spezifiziert, wird ein **`100nF`** Kondensator zwischen die Pins BOOT und SW geschaltet.
+
+*(Anmerkung: C1 und C2 können für eine vereinfachte Stückliste auch durch den gleichen `22µF / 25V` Kondensator ersetzt werden.)*
+
+## 3. Finale Stückliste (BOM) für LCSC/JLCPCB
+
+Diese Liste wurde auf Verfügbarkeit geprüft (Stand: 24. Juni 2025).
+
+| Bauteil (Ref) | Wert | LCSC Part # | Gehäuse | JLCPCB Status | Hinweis |

+
+## 4. Wichtige Hinweise zum Layout
+
+Für einen hochfrequenten Wandler (1MHz) ist ein gutes Layout noch wichtiger als sonst.
+
+1.  **Kritischer Loop (Eingang):** Der Pfad vom Eingangskondensator `C1` zum `VIN`-Pin des ICs und vom `GND`-Pin des ICs zurück zu `C1` muss absolut minimal sein. Kurze, breite Leiterbahnen sind hier Pflicht.
+2.  **SW (Schaltknoten):** Der Pin `SW` (Switch) führt die hochfrequent geschaltete Spannung. Die Leiterbahn von diesem Pin zur Spule `L1` sollte kurz und breit sein, aber von empfindlichen Signalen (wie der Feedback-Leitung) ferngehalten werden.
+3.  **Feedback-Pfad:** Die Widerstände `R1` und `R2` sollten nah am `FB`-Pin des ICs platziert werden. Die Leiterbahn vom `FB`-Pin zum Widerstandsteiler sollte kurz sein und nicht parallel zu lauten Leiterbahnen (wie SW) geführt werden.
+4.  **Masseführung:** Eine durchgehende Massefläche unter den Komponenten ist die beste Lösung, um die Rückströme kurz zu halten und die thermische Anbindung zu verbessern.
+
+## 5. Berechnung des Wirkungsgrads
+
+Dieses Kapitel analysiert die Verlustleistung und den Gesamtwirkungsgrad der Schaltung für verschiedene Lastfälle.
+
+### 5.1 Verlustleistung des Feedback-Netzwerks
+
+Das Feedback-Netzwerk zur Einstellung der Ausgangsspannung hat einen permanenten, aber sehr geringen Stromverbrauch.
+
+* **Widerstände:** $R_{total} = R1 + R2 = 120kΩ + 27kΩ = 147kΩ$
+* **Leistung:** $P = V^2 / R = (3.27V)^2 / 147000Ω = 10.69W / 147000Ω \approx 0.0000727W$
+
+Der statische Verlust im Feedback-Netzwerk beträgt somit nur ca. **73 µW** und ist für die Gesamteffizienz vernachlässigbar.
+
+### 5.2 Gesamtwirkungsgrad
+
+Die Berechnung basiert auf den typischen Werten aus dem SY8120IABC-Datenblatt und den gewählten externen Komponenten.
+
+**Parameter für die Berechnung:**
+
+* Eingangsspannung ($V_{in}$): 12 V
+* Ausgangsspannung ($V_{out}$): 3.27 V
+* Tastverhältnis ($D$): $3.27V / 12V \approx 0.273$
+* $R_{DS(on)}$ High-Side MOSFET: 130 mΩ (0.13 Ω)
+* $R_{DS(on)}$ Low-Side MOSFET: 105 mΩ (0.105 Ω)
+* Induktor-Widerstand (DCR): 30 mΩ (0.03 Ω) (für die `CR5040-4R7M`)
+* Ruhestrom ($I_Q$): ca. 200 µA (0.0002 A)
+
+---
+
+#### Fall 1: Laststrom $I_{out}$ = 100 mA (0.1 A)
+
+* **Ausgangsleistung ($P_{out}$):** $3.27V \times 0.1A = \mathbf{327\ mW}$
+* **Hauptverluste ($P_{loss}$):**
+    * IC Leitverluste (High-Side): $(0.1A)^2 \times 0.13Ω \times 0.273 \approx 0.36\ mW$
+    * IC Leitverluste (Low-Side): $(0.1A)^2 \times 0.105Ω \times (1-0.273) \approx 0.76\ mW$
+    * Spulenverlust (DCR): $(0.1A)^2 \times 0.03Ω = 0.3\ mW$
+    * IC Ruhestromverlust: $12V \times 200µA = 2.4\ mW$
+    * Schalt- & Treiberverluste (geschätzt): ca. **15 mW**
+* **Gesamtverlust:** $\approx 0.36 + 0.76 + 0.3 + 2.4 + 15 = 18.8\ mW$
+* **Gesamteffizienz ($\eta$):** $\frac{327mW}{327mW + 18.8mW} \times 100\% \approx \mathbf{94.5\%}$
+
+---
+
+#### Fall 2: Laststrom $I_{out}$ = 300 mA (0.3 A)
+
+* **Ausgangsleistung ($P_{out}$):** $3.27V \times 0.3A = \mathbf{981\ mW}$
+* **Hauptverluste ($P_{loss}$):**
+    * IC Leitverluste (High-Side): $(0.3A)^2 \times 0.13Ω \times 0.273 \approx 3.2\ mW$
+    * IC Leitverluste (Low-Side): $(0.3A)^2 \times 0.105Ω \times (1-0.273) \approx 6.8\ mW$
+    * Spulenverlust (DCR): $(0.3A)^2 \times 0.03Ω = 2.7\ mW$
+    * IC Ruhestromverlust: $12V \times 200µA = 2.4\ mW$
+    * Schalt- & Treiberverluste (geschätzt): ca. **35 mW**
+* **Gesamtverlust:** $\approx 3.2 + 6.8 + 2.7 + 2.4 + 35 = 50.1\ mW$
+* **Gesamteffizienz ($\eta$):** $\frac{981mW}{981mW + 50.1mW} \times 100\% \approx \mathbf{95.1\%}$
+
+---
+
+#### Fall 3: Laststrom $I_{out}$ = 500 mA (0.5 A)
+
+* **Ausgangsleistung ($P_{out}$):** $3.27V \times 0.5A = \mathbf{1635\ mW}$
+* **Hauptverluste ($P_{loss}$):**
+    * IC Leitverluste (High-Side): $(0.5A)^2 \times 0.13Ω \times 0.273 \approx 8.9\ mW$
+    * IC Leitverluste (Low-Side): $(0.5A)^2 \times 0.105Ω \times (1-0.273) \approx 19.1\ mW$
+    * Spulenverlust (DCR): $(0.5A)^2 \times 0.03Ω = 7.5\ mW$
+    * IC Ruhestromverlust: $12V \times 200µA = 2.4\ mW$
+    * Schalt- & Treiberverluste (geschätzt): ca. **60 mW**
+* **Gesamtverlust:** $\approx 8.9 + 19.1 + 7.5 + 2.4 + 60 = 97.9\ mW$
+* **Gesamteffizienz ($\eta$):** $\frac{1635mW}{1635mW + 97.9mW} \times 100\% \approx \mathbf{94.4\%}$
+
+### 5.3 Zusammenfassung der Effizienz
+
+| Laststrom | Geschätzter Gesamtwirkungsgrad |
+| :--- | :--- |
+| **100 mA** | **~ 94.5%** |
+| **300 mA** | **~ 95.1%** |
+| **500 mA** | **~ 94.4%** |
+
+Der Wirkungsgrad des synchronen Designs ist durchgehend exzellent und übertrifft den eines vergleichbaren nicht-synchronen Wandlers deutlich. Der Hauptgrund sind die massiv geringeren Leitverluste, da anstelle einer Diode mit hohem Spannungsabfall ein MOSFET mit niedrigem $R_{DS(on)}$ als Freilaufelement dient.

+# Design: 12V to 3.3V Step-Down with SY8120IABC
+
+This document describes the design of a high-efficiency, synchronous DC/DC step-down converter. It serves as a modern alternative to older designs like the TPS5430.
+
+## 1. Design Goals
+
+* **Input Voltage ($V_{in}$):** 12V (Range 10.5V - 14V)
+* **Output Voltage ($V_{out}$):** 3.3V
+* **Output Current ($I_{out}$):** Designed for approx. 0.5A, with reserves up to 2A.
+* **Core Component:** Silergy SY8120IABC (Synchronous, 1MHz, up to 18V, 2A)
+* **Objectives:** High efficiency, compact layout, minimal number of external components (no external diode).
+
+## 2. Component Design
+
+The calculation of the external components is based on the datasheet of the SY8120IABC.
+
+![Schema SY8120I](SY8129I_Schematics.svg Schematics for calculations)
+
+### a) Feedback Resistors (R1, R2) - Optimized for "Basic Parts"
+
+To use common and cost-effective "Basic Parts" from JLCPCB, resistors from the E24 series are chosen. The goal is to match the required voltage ratio for approx. 3.3V as closely as possible.
+
+The reference voltage ($V_{FB}$) of the SY8120IABC is **0.6V**.
+
+An excellent combination available as "Basic Parts" is:
+* **`R1` (upper resistor) = 120 kΩ**
+* **`R2` (lower resistor) = 27 kΩ**
+
+The resulting output voltage is calculated as follows:
+$V_{out} = 0.6V \times (1 + \frac{R1}{R2}) = 0.6V \times (1 + \frac{120kΩ}{27kΩ}) \approx \mathbf{3.27V}$
+
+This output voltage is ideal and completely safe for all target components.
+
+### b) Inductor (L1)
+
+Due to the high switching frequency of 1 MHz, a physically small inductor with a lower inductance value can be used. The datasheet recommends values in the range of 2.2µH to 10µH.
+
+* We choose a value of **`L1 = 4.7 µH`**.
+* **Important:** The saturation current ($I_{sat}$) must be higher than the IC's current limit (approx. 3A). An inductor with **$I_{sat} > 3A$** is selected.
+
+### c) Capacitors (C1, C2, C3)
+
+* **Input Capacitor (C1):** A **`10µF / 25V`** ceramic capacitor (0805) is sufficient to stabilize the input voltage.
+* **Output Capacitor (C2):** A **`22µF / 10V`** ceramic capacitor (0805) is recommended for a stable output voltage with low ripple.
+* **Bootstrap Capacitor (C3):** As specified in the datasheet, a **`100nF`** capacitor is connected between the BOOT and SW pins.
+
+*(Note: As discussed later, C1 and C2 can also be replaced by the same `22µF / 25V` capacitor for a simplified Bill of Materials.)*

+
+## 4. Important Layout Notes
+
+For a high-frequency converter (1MHz), a good layout is even more critical than usual.
+
+1.  **Critical Loop (Input):** The path from the input capacitor `C1` to the `VIN` pin of the IC, and from the `GND` pin of the IC back to `C1`, must be absolutely minimal. Short, wide traces are mandatory here.
+2.  **SW (Switching Node):** The `SW` pin carries the high-frequency switched voltage. The trace from this pin to the inductor `L1` should be short and wide, but kept away from sensitive signals (like the feedback line).
+3.  **Feedback Path:** The resistors `R1` and `R2` should be placed close to the `FB` pin of the IC. The trace from the `FB` pin to the resistor divider should be short and should not be routed parallel to noisy traces (like SW).
+4.  **Grounding:** A continuous ground plane underneath the components is the best solution to keep return paths short and improve thermal performance.
+
+## 5. Efficiency Calculation (SY8120IABC Design)
+
+This chapter analyzes the power loss and overall efficiency of the circuit for different load cases.
+
+### 5.1 Power Loss of the Feedback Network
+
+The feedback network for setting the output voltage has a permanent but very low power consumption.
+
+* **Resistors:** $R_{total} = R1 + R2 = 120kΩ + 27kΩ = 147kΩ$
+* **Power:** $P = V^2 / R = (3.27V)^2 / 147000Ω \approx 0.0000727W$
+
+The static loss in the feedback network is therefore only about **73 µW** and is negligible for the overall efficiency.
+
+### 5.2 Overall Efficiency
+
+The calculation is based on typical values from the SY8120IABC datasheet and the selected external components.
+
+**Parameters for Calculation:**
+
+* Input Voltage ($V_{in}$): 12 V
+* Output Voltage ($V_{out}$): 3.27 V
+* Duty Cycle ($D$): $3.27V / 12V \approx 0.273$
+* $R_{DS(on)}$ High-Side MOSFET: 130 mΩ (0.13 Ω)
+* $R_{DS(on)}$ Low-Side MOSFET: 105 mΩ (0.105 Ω)
+* Inductor Resistance (DCR): 65 mΩ (0.065 Ω) (for the `SMDRI127-330MT`)
+* Quiescent Current ($I_Q$): approx. 200 µA (0.0002 A)
+
+---
+
+#### Case 1: Load Current $I_{out}$ = 100 mA (0.1 A)
+
+* **Output Power ($P_{out}$):** $3.27V \times 0.1A = \mathbf{327\ mW}$
+* **Main Losses ($P_{loss}$):**
+    * IC Conduction Loss (High-Side): $(0.1A)^2 \times 0.13Ω \times 0.273 \approx 0.36\ mW$
+    * IC Conduction Loss (Low-Side): $(0.1A)^2 \times 0.105Ω \times (1-0.273) \approx 0.76\ mW$
+    * Inductor Loss (DCR): $(0.1A)^2 \times 0.065Ω = 0.65\ mW$
