Description and Introduction

2.25MHz 300mA Step-Down Converter in 2x2mm SON/TSOT23 Package 5-SOT -40 to 85 The TPS62240DDCT is a synchronous step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable (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 TPS62240DDCT is a high-efficiency, low-quiescent-current buck converter designed for battery-powered applications.  
- It operates in PWM mode at higher loads and automatically switches to power-save mode at light loads to improve efficiency.  
- The device includes integrated synchronous rectification, eliminating the need for an external Schottky diode.  

### **Features:**
- **High Efficiency:** Optimized for low-power applications with up to 95% efficiency.  
- **Low Quiescent Current:** 15µA (typical) extends battery life.  
- **Fixed-Frequency Operation:** 2.25MHz switching frequency allows for small external components.  
- **100% Duty Cycle Mode:** Supports low-dropout operation for extended battery life.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation under fault conditions.  

This device is commonly used in portable electronics, IoT devices, and other battery-powered applications requiring efficient power conversion.
