Description and Introduction

Synchronous rectifier step up converter The **L6920DB** is a **synchronous step-down DC-DC converter** manufactured by **STMicroelectronics (ST)**. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.9V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.6V to VIN  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 1.4MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** **SO-8**  

### **Descriptions:**
- The L6920DB is a **high-efficiency, synchronous step-down DC-DC converter** designed for battery-powered applications.  
- It integrates **N-channel and P-channel MOSFETs** for synchronous rectification, improving efficiency.  
- Features **PWM mode** for high efficiency at heavy loads and **PFM mode** for improved efficiency at light loads.  
- Includes **internal soft-start** and **overcurrent/thermal protection**.  

### **Features:**
- **Synchronous rectification** for high efficiency.  
- **1.4MHz fixed switching frequency** (allows small external components).  
- **Automatic PWM/PFM mode switching** for optimized efficiency.  
- **100% duty cycle operation** (for low dropout).  
- **Internal soft-start** (reduces inrush current).  
- **Short-circuit and thermal protection**.  
- **Low quiescent current** (improves battery life).  

This information is strictly based on the manufacturer's datasheet.
