Description and Introduction

Synchronous rectifier step up converter The L6920DCTR is a synchronous step-down switching regulator manufactured by STMicroelectronics (STM). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.6V to VIN  
- **Output Current:** Up to 1.2A  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 30µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DFN6 (3x3mm)  

### **Descriptions:**  
- The L6920DCTR is a high-efficiency, synchronous step-down DC-DC converter optimized for battery-powered applications.  
- It integrates power MOSFETs, reducing external component count.  
- Operates in PWM mode for high efficiency under heavy loads and automatically switches to PFM mode at light loads to improve efficiency.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power dissipation.  
- **100% Duty Cycle Operation:** Allows dropout operation when input voltage approaches output voltage.  
- **Internal Soft-Start:** Limits inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation when input voltage is too low.  
- **Short-Circuit Protection:** Includes overcurrent and thermal shutdown protection.
