Description and Introduction

DDR1, DDR2, DDR3 Switcher and LDO 24-VQFN -40 to 85 The TPS51116RGETG4 is a synchronous buck controller manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.76V to 5.5V (adjustable)  
- **Switching Frequency:** 300kHz to 2MHz (adjustable)  
- **Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 24-VQFN (4mm x 4mm)  

### **Descriptions:**
- The TPS51116RGETG4 is a high-efficiency synchronous buck controller designed for point-of-load (POL) applications.  
- It supports pre-biased outputs and provides precise voltage regulation.  
- The device integrates gate drivers for external N-channel MOSFETs and includes adaptive dead-time control.  

### **Features:**
- **Adjustable Output Voltage:** Uses external resistor divider.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Overcurrent Protection (OCP):** Uses inductor DCR sensing or external resistor.  
- **Thermal Shutdown:** Protects against overheating.  
- **Synchronization Capability:** Supports external clock input.  
- **Low Quiescent Current:** Improves light-load efficiency.  

This device is commonly used in industrial, networking, and computing applications requiring high-efficiency power conversion.
