Description and Introduction

2.25MHz 300mA Step-Down Converter in 2x2mm SON/TSOT23 Package 6-WSON -40 to 85 The TPS62240DRVR is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **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:** 17µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-pin WSON (DRV)  

### **Descriptions:**  
The TPS62240DRVR is a high-efficiency, low-quiescent-current synchronous step-down converter designed for battery-powered applications. It operates at a fixed frequency of 2.25MHz, enabling the use of small external components. The device supports a wide input voltage range, making it suitable for single-cell Li-ion or multi-cell alkaline/NiMH applications.  

### **Features:**  
- **High Efficiency:** Up to 95% power conversion efficiency.  
- **Low Quiescent Current:** 17µA (typical) for extended battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **100% Duty Cycle Mode:** Supports low dropout operation.  
- **Power-Save Mode:** Improves efficiency at light loads.  
- **Integrated Synchronous Rectifier:** Reduces external component count.  
- **Thermal Shutdown & Overcurrent Protection:** Enhances reliability.  

This information is based solely on the manufacturer's datasheet and product documentation.
