Description and Introduction

HIGH EFFICIENCY MONOLITHIC SYNCHRONOUS STEP DOWN REGULATOR The L6926 is a high-efficiency synchronous step-down DC-DC converter manufactured by STMicroelectronics.  

### **Key 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) in PFM mode  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin DFN (3x3mm)  

### **Descriptions:**  
- The L6926 is a synchronous buck converter with integrated power switches.  
- It supports Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) for improved efficiency at light loads.  
- Features a low-dropout (LDO) mode for extended battery life.  
- Includes overcurrent, overvoltage, and thermal shutdown protection.  

### **Features:**  
- **High Efficiency:** Synchronous rectification and low RDS(ON) MOSFETs.  
- **Low Power Consumption:** Ultra-low quiescent current in PFM mode.  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Soft-Start:** Prevents inrush current at startup.  
- **Compact Design:** Small footprint with minimal external components.  
- **Protection Features:** Overcurrent, overvoltage, and thermal shutdown.
