Description and Introduction

3.3-V, 1.5-A, 17-V Vin Step-Down Converter in QFN-16 16-QFN -40 to 85 The TPS62111RSAR is a step-down (buck) DC-DC converter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features 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 A  
- **Switching Frequency:** 1.25 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17 µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QFN (RSAR)  

### **Descriptions:**
- The TPS62111 is a synchronous step-down converter designed for low-power applications.  
- It operates with high efficiency across a wide input voltage range, making it suitable for battery-powered systems.  
- The device features a fixed-frequency PWM mode for stable operation under load and a power-save mode for light-load efficiency.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Low Quiescent Current:** 17 µA (typical) for improved battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **Integrated Soft-Start:** Prevents inrush current at startup.  
- **Overcurrent & Thermal Protection:** Ensures safe operation.  
- **Synchronization Capability:** Can sync to an external clock.  

This information is based solely on TI's official datasheet for the TPS62111RSAR.
