Description and Introduction

1.8V to 28V Input Sync. Step Down Controller with DCAP? Mode, Optimized for Light Load Efficiency 14-VQFN -40 to 85 The TPS51117RGYR is a synchronous buck controller manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.76V to 5.5V  
- **Switching Frequency:** Adjustable (250kHz to 700kHz)  
- **Output Current:** Up to 10A (dependent on external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 20-pin VQFN (RGY)  

### **Descriptions:**  
The TPS51117RGYR is a high-efficiency synchronous buck controller designed for notebook and desktop power applications. It supports a wide input voltage range and provides precise output voltage regulation. The device features adaptive on-time control for fast transient response and operates in either forced PWM or automatic DCM mode for improved efficiency at light loads.  

### **Features:**  
- **Adaptive On-Time Control** for fast transient response  
- **Adjustable Switching Frequency** (250kHz to 700kHz)  
- **Programmable Soft-Start**  
- **Power Good Output** for monitoring  
- **Overcurrent Protection (OCP)** and **Overvoltage Protection (OVP)**  
- **Thermal Shutdown**  
- **Supports Pre-Biased Outputs**  
- **Low Quiescent Current** in standby mode  

This information is based on TI's official datasheet for the TPS51117RGYR.
