Description and Introduction

5-V, 1.5-A, 17-V Vin Step-Down Converter in QFN-16 16-QFN -40 to 85 The TPS62112RSARG4 is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 3 V to 17 V  
- **Output Voltage Range:** 0.9 V to 6 V (adjustable)  
- **Output Current:** Up to 1.2 A  
- **Switching Frequency:** 1.25 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QFN (3 mm × 3 mm)  

### **Descriptions:**  
The TPS62112RSARG4 is a synchronous step-down converter with integrated power switches. It is designed for small, low-power applications requiring high efficiency and a compact footprint. The device operates in pulse-width modulation (PWM) mode and includes features like soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency with integrated synchronous rectification.  
- **Low Quiescent Current:** 17 µA (typical) in power-save mode.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Fixed-Frequency Operation:** 1.25 MHz switching frequency reduces external component size.  
- **Protection Features:** Overcurrent, overtemperature, and undervoltage lockout (UVLO).  
- **Small Footprint:** 16-pin QFN package (3 mm × 3 mm) for space-constrained applications.  

This device is commonly used in battery-powered systems, industrial applications, and portable electronics.
