Description and Introduction

1.8-V Output, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 5-SOT -40 to 85 The TPS62222DDCRG4 is a synchronous step-down DC-DC converter manufactured by Texas Instruments (TI).  

### **Key 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:** SOT-23-5 (DDC)  

### **Descriptions and Features:**  
- Ultra-small, high-efficiency synchronous step-down converter.  
- Fixed-frequency PWM operation for low output voltage ripple.  
- Automatic power-save mode for improved efficiency at light loads.  
- 100% duty cycle mode for low dropout operation.  
- Internal soft-start to limit inrush current.  
- Over-temperature protection and short-circuit protection.  
- Suitable for battery-powered portable applications.  

This device is designed for space-constrained applications requiring high efficiency and low power consumption.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • TPS62222DDCR --: Same TPS62222 converter in the same SOT-23-5 (DDC) package; only the G4 lead-free/Green suffix differs, so it is a drop-in replacement.
  • TPS62220DDCR --: Same TPS6222x family with identical pinout and package; lower fixed output voltage variant, usable where the exact output voltage is not critical.
  • TPS62203DBVR --: Similar 1.8V-class step-down converter in SOT-23-5 with comparable current rating; check output voltage and switching frequency before substituting.
