Description and Introduction

1.8-V Output, 800-mA, 10V Vin, 95% Efficient Step-Down Converter in MSOP-10 The TPS62054DGSR G4 is a synchronous step-down converter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 2.5 V to 6 V  
- **Output Voltage Range:** Adjustable from 0.8 V to 5 V  
- **Output Current:** Up to 1.5 A  
- **Switching Frequency:** 2.25 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17 µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VSSOP-10 (DGS)  

### **Descriptions:**  
- The TPS62054DGSR G4 is a high-efficiency, low-quiescent-current synchronous step-down DC-DC converter.  
- It is designed for battery-powered portable applications, providing a regulated output voltage from an input supply as low as 2.5 V.  
- The device operates in PWM mode at higher loads and automatically switches to Power Save Mode (PSM) at light loads to improve efficiency.  

### **Features:**  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Low Quiescent Current:** 17 µA (typical) for improved battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Fixed-Frequency Operation:** 2.25 MHz allows for small external components.  
- **100% Duty Cycle Mode:** Supports low dropout operation.  
- **Overcurrent and Thermal Protection:** Ensures safe operation.  
- **Power Save Mode (PSM):** Enhances efficiency at light loads.  

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