- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin VSSOP (DGQ)  

### **Descriptions:**  
The TPS62044DGQRG4 is a high-efficiency, synchronous step-down DC-DC converter designed for portable and battery-powered applications. It operates at a high switching frequency, allowing the use of small external components. The device supports forced PWM and power-save modes for improved efficiency across load conditions.  

### **Features:**  
- **High Efficiency Synchronous Buck Converter**  
- **Adjustable Output Voltage (0.8 V to 5 V)**  
- **1.5-A Output Current Capability**  
- **2.25-MHz Fixed Switching Frequency**  
- **Low Quiescent Current (17 µA typical)**  
- **100% Duty Cycle for Lowest Dropout**  
- **Power-Save Mode for Light Load Efficiency**  
- **Internal Soft-Start and Over-Temperature Protection**  
- **Available in a 10-Pin VSSOP Package**  

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