Description and Introduction

3.3-V Output, 300-mA, 95% Efficient Step-Down Converter in SOT-23 The TPS62203DBVRG4 is a step-down DC-DC converter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.7V to VIN  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The TPS62203DBVRG4 is a high-efficiency, synchronous step-down converter designed for low-power applications. It operates in pulse-frequency modulation (PFM) mode at light loads to improve efficiency and transitions to pulse-width modulation (PWM) mode for higher loads.  

### **Features:**  
- **High Efficiency:** Up to 95%  
- **Low Quiescent Current:** 15µA (typical)  
- **Adjustable Output Voltage:** 0.7V to VIN  
- **Fixed Switching Frequency:** 1.25MHz  
- **Synchronous Rectification:** Improves efficiency  
- **100% Duty Cycle Mode:** Supports low dropout operation  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Undervoltage Lockout (UVLO):** Ensures proper operation
