Description and Introduction

1.8-V Output, 300-mA, 95% Efficient Step-Down Converter in SOT-23 The TPS62202DBVR is a high-efficiency synchronous step-down DC-DC converter manufactured by Texas Instruments (TEXAS). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.7V to VIN  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**
- The TPS62202DBVR is a compact, low-power step-down converter designed for battery-powered applications.  
- It operates in PWM mode under heavy loads and automatically switches to power-save mode (PFM) at light loads to improve efficiency.  
- The device includes built-in soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**
- **High Efficiency:** Optimized for low-power applications.  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **Fixed-Frequency Operation:** Reduces noise and simplifies filtering.  
- **Synchronous Rectification:** Improves efficiency by eliminating external Schottky diodes.  
- **Small Form Factor:** SOT-23-5 package saves board space.  
- **Adjustable Output Voltage:** Set via external resistors.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application circuits, refer to the official Texas Instruments documentation.
