Description and Introduction

3.3-V Output, 300-mA, 95% Efficient Step-Down Converter in SOT-23 The TPS62203DBVR is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features from Ic-phoenix technical data files:

### **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 (DBV)  

### **Descriptions:**
- The TPS62203DBVR is a high-efficiency, step-down DC-DC converter optimized for low-power applications.  
- It operates in a pulse-frequency modulation (PFM) mode at light loads to improve efficiency.  
- The device is designed for battery-powered portable applications requiring extended battery life.  

### **Features:**
- **Low Quiescent Current:** 15µA (typical) for improved efficiency in standby mode.  
- **Synchronous Rectification:** Improves efficiency and reduces external component count.  
- **Fixed-Frequency Operation:** 1.25MHz switching frequency minimizes external component size.  
- **100% Duty Cycle Mode:** Allows lowest possible dropout voltage.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This information is based on the manufacturer's datasheet and technical documentation.
