Description and Introduction

1V HIGH EFFICIENCY SYNCHRONOUS STEP UP CONVERTER The L6920DTR is a synchronous step-down switching regulator manufactured by STMicroelectronics. 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:** 25µA (typical) in PFM mode  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DFN8 (3x3mm)  

### **Descriptions:**
- The L6920DTR is a high-efficiency, synchronous step-down DC-DC converter designed for battery-powered applications.  
- It integrates low RDS(on) power MOSFETs to minimize power losses.  
- Supports both Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes for optimized efficiency across load conditions.  
- Features a fixed-frequency operation in PWM mode and automatic PFM mode at light loads.  

### **Features:**
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  
- **Low Dropout Operation:** Allows the output to stay regulated even when the input voltage is close to the output voltage.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Short-Circuit Protection:** Includes overcurrent and thermal shutdown protection.  
- **100% Duty Cycle Operation:** Ensures continuous power delivery when the input voltage drops close to the output voltage.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  

This information is based on the manufacturer's datasheet for the L6920DTR.
