Description and Introduction

2.25MHz 1A Step-Down Converter in 2x2mm SON Package 6-WSON -40 to 85 The TPS62290DRVR is a 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 from 0.6V to VIN  
- **Output Current:** Up to 2A  
- **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 TPS62290DRVR is a high-efficiency, 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 forced PWM and Power Save modes for optimized efficiency across load conditions.  

### **Features:**  
- High efficiency across a wide load range  
- Adjustable output voltage via external resistors  
- Power Save mode for light-load efficiency  
- 100% duty cycle for lowest dropout  
- Integrated synchronous rectifier  
- Over-temperature and over-current protection  
- Small solution size with minimal external components  

This information is sourced from the official TI datasheet for the TPS62290DRVR.
