Description and Introduction

HIGH-EFFICIENCY, SOT23 STEP-DOWN, DC-DC CONVERTER The TPS62208DBVRG4 is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.6V 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 TPS62208DBVRG4 is a high-efficiency, low-quiescent-current synchronous step-down converter.  
- It is designed for battery-powered portable applications requiring extended battery life.  
- The device operates in PWM mode under medium to heavy load conditions and automatically enters Power Save Mode (PSM) at light loads for improved efficiency.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency with integrated synchronous rectification.  
- **Low Quiescent Current:** 15µA (typical) for extended battery life.  
- **Fixed-Frequency Operation:** 1.25MHz switching frequency reduces external component size.  
- **100% Duty Cycle Mode:** Allows lowest dropout operation.  
- **Power Save Mode:** Improves efficiency at light loads.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation.  
- **Small Footprint:** SOT-23-5 package saves board space.  

This device is commonly used in portable electronics, wireless sensors, and battery-powered applications.

Application Scenarios & Design Considerations

HIGH-EFFICIENCY, SOT23 STEP-DOWN, DC-DC CONVERTER

Alternative Part Number

  • TPS62200DBVR --: Same TPS6220x family step-down converter in the same SOT-23-5 package with similar input range and pinout, making it a close drop-in choice when the exact output voltage variant is not critical.
  • AP3402KTR-G1 --: Pin-compatible 2A synchronous buck converter in SOT-23-5 with wide input range and adjustable output, offering a different vendor and series as a functional substitute.
  • MP2145GD-Z --: Compact high-efficiency synchronous step-down converter in a small package with comparable current capability, suitable as an alternative from a different manufacturer and series.
  • TPS62203DBVR --: Sister part in the TPS6220x series with the same package and pin configuration; fixed 1.8V output version that is electrically compatible for many 1.8V rail applications.
  • TPS62207DBVR --: Another TPS6220x family member in the same SOT-23-5 footprint with matching pinout and similar current rating; fixed 1.2V output variant suitable as a functional replacement where the output voltage matches.
