Description and Introduction

5-V, 1.5-A, 17-V Vin Step-Down Converter in QFN-16 16-QFN -40 to 85 The TPS62112RSAR is a step-down (buck) DC-DC converter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 3 V to 17 V  
- **Output Voltage Range:** Adjustable from 0.9 V to 6 V  
- **Output Current:** Up to 1.5 A  
- **Switching Frequency:** 1.25 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QFN (RSAR)  

### **Descriptions:**
- The TPS62112RSAR is a synchronous step-down converter with integrated power MOSFETs.  
- It is designed for high efficiency and low power consumption in battery-powered applications.  
- Features a fixed-frequency PWM operation for stable performance.  
- Includes overcurrent, overvoltage, and thermal shutdown protection.  

### **Features:**
- **High Efficiency:** Up to 95% efficiency with integrated synchronous rectification.  
- **Adjustable Output:** Output voltage can be set via an external resistor divider.  
- **Low Quiescent Current:** 17 µA (typical) in power-save mode.  
- **Power-Save Mode:** Improves efficiency at light loads.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Synchronization Capability:** Can be synchronized to an external clock.  
- **Protection Features:** Overcurrent, overvoltage, and thermal shutdown.  

This information is based on TI's official datasheet and product documentation.
