Description and Introduction

400-mA, 1.25-MHz, HIGH-EFFICIENCY, STEP-DOWN CONVERTER IN THIN-SOT23 The TPS62220DDC is a step-down DC-DC converter manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 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 (DDC), 5-pin  

### **Descriptions:**
- The TPS62220DDC is a high-efficiency, low-quiescent-current synchronous step-down converter.  
- It is designed for battery-powered portable applications requiring extended battery life.  
- The device operates in PWM mode at higher loads and automatically switches to power-save mode at light loads for improved efficiency.  
- It features a fixed-frequency operation to minimize output voltage ripple.  

### **Features:**
- **High Efficiency:** Up to 95% efficiency due to synchronous rectification.  
- **Low Quiescent Current:** 15µA (typical) for improved battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **100% Duty Cycle Mode:** Allows lowest dropout voltage.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Over-Temperature Protection:** Safeguards the device.  
- **Small Footprint:** SOT-23 package for space-constrained applications.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
