Description and Introduction

1.7-V Output, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 The TPS62229DDCT is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on factual information:

### **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-23-6 (DDC)  

### **Descriptions:**  
- The TPS62229DDCT is a high-efficiency, low-quiescent-current synchronous step-down converter optimized for battery-powered applications.  
- It operates in PWM mode under medium to heavy loads and automatically switches to power-save mode at light loads to improve efficiency.  
- The device includes built-in soft-start and over-temperature protection.  

### **Features:**  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Low Quiescent Current:** 15µA (typical) extends battery life.  
- **Fixed-Frequency Operation:** 2.25MHz allows the use of small external components.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **100% Duty Cycle Mode:** Supports low dropout operation.  
- **Over-Temperature Protection:** Safeguards the device under fault conditions.  
- **Adjustable Output Voltage:** Set via external resistors.  

This information is based on TI's official datasheet for the TPS62229DDCT.
