Description and Introduction

1.6-V Output, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 5-SOT -40 to 85 The TPS62224DDCRG4 is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6 (DDC)  

### **Descriptions:**  
- The TPS62224DDCRG4 is a high-efficiency, low-quiescent-current synchronous step-down converter optimized for battery-powered applications.  
- It operates in Pulse Frequency Modulation (PFM) mode at light loads to improve efficiency and transitions to fixed-frequency PWM mode at higher loads.  
- The device includes built-in soft-start and over-temperature protection.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency due to synchronous rectification.  
- **Low Quiescent Current:** 17µA (typical) for extended battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Fixed-Frequency Operation:** 2.25MHz switching frequency reduces external component size.  
- **100% Duty Cycle Mode:** Supports low dropout operation.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **Protection Features:** Over-temperature and short-circuit protection.  

This information is strictly factual and sourced from TI's official documentation.
