Description and Introduction

Adjustable, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 5-SOT -40 to 85 The TPS62220DDCTG4 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 0.6V 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:** 8-pin SON (3mm x 3mm)  

**Descriptions and Features:**  
- High-efficiency synchronous step-down converter  
- Low quiescent current for improved battery life  
- Fixed-frequency PWM operation with automatic power-save mode  
- 100% duty cycle for lowest dropout  
- Internal soft-start and over-temperature protection  
- Adjustable output voltage via external resistors  
- Small solution size due to high switching frequency  

This device is designed for portable and battery-powered applications requiring high efficiency and compact size.

Application Scenarios & Design Considerations

Adjustable, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 5-SOT -40 to 85

Alternative Part Number

  • TPS62203DBVR --: Same TPS6220x family step-down converter in a SOT-23-5 package with similar input range and current rating, suitable drop-in for many 3.3V/1.8V rail designs.
  • AP3211KTR-G1 --: Pin-compatible 1A synchronous buck converter in SOT-23-5 with wide input range, a common second-source for small step-down regulators.
  • MP2359DJ-LF-Z --: 1.2A step-down converter in TSOT-23-5 with comparable input voltage and switching frequency, usable as an alternative with minor layout adjustment.
