Description and Introduction

1.6-V Output, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 The TPS62224DDCR is a step-down DC-DC converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **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:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DDC)  

### **Descriptions:**
- The TPS62224DDCR is a high-efficiency, low-quiescent-current synchronous step-down converter optimized for battery-powered applications.  
- It operates in **Pulse-Width Modulation (PWM)** mode for constant frequency regulation under load and automatically switches to **Power Save Mode (PSM)** at light loads to improve efficiency.  
- The device integrates both high-side and low-side MOSFETs, reducing external component count.  

### **Features:**
- **High Efficiency:** Up to 95% efficiency with integrated synchronous rectification.  
- **Low Quiescent Current:** 15µA (typical) for extended battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **100% Duty Cycle Mode:** Allows operation at very low input voltages.  
- **Over-Temperature Protection:** Shuts down if the junction temperature exceeds safe limits.  
- **Short-Circuit Protection:** Includes hiccup mode for fault recovery.  
- **Small Footprint:** SOT-23-5 package for space-constrained applications.
