Description and Introduction

Adjustable, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 The TPS62220DDCRG4 is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable (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 (DDC)  

### **Descriptions:**  
- The TPS62220DDCRG4 is a high-efficiency, low-quiescent-current synchronous step-down converter.  
- It is designed for battery-powered portable applications requiring small size and high efficiency.  
- The device operates in Pulse Frequency Modulation (PFM) mode at light loads to improve efficiency.  

### **Features:**  
- **High Efficiency:** Up to 95% power conversion efficiency.  
- **Low Quiescent Current:** 15µA typical for extended battery life.  
- **Fixed-Frequency Operation:** 2.25MHz switching frequency minimizes external component size.  
- **100% Duty Cycle Mode:** Allows lowest dropout voltage.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation.  
- **Small Footprint:** SOT-23-5 package for space-constrained applications.

Application Scenarios & Design Considerations

Adjustable, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23

Alternative Part Number

  • TPS62220DDCR --: Same TPS62220 buck converter in the same SOT-23-5 (DDC) package, identical electrical specifications; only the G4 lead-free/Green suffix differs, making it a direct drop-in replacement.
  • TPS62203DBVR --: Same TPS6220x family 300 mA step-down converter with similar input range and fixed output option, available in SOT-23-5; a close functional substitute when exact output voltage trimming is acceptable.
  • AP3211KTR-G1 --: Alternative 1.5 A synchronous buck converter in a small SOT-23-5 style package with comparable input voltage range, usable as a cross-vendor replacement for low-current step-down applications.
