Description and Introduction

DDR1, DDR2, DDR3 Switcher and LDO 24-VQFN -40 to 85 The TPS51116RGER is a synchronous buck controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.76V to 5.5V (adjustable)  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Maximum Output Current:** Supports up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin VQFN (RGER)  

### **Descriptions:**  
- The TPS51116RGER is a high-efficiency synchronous buck controller designed for point-of-load (POL) power supplies.  
- It integrates gate drivers for external N-channel MOSFETs and supports adaptive on-time control for fast transient response.  
- Suitable for applications such as servers, networking equipment, and industrial systems.  

### **Features:**  
- **Adaptive On-Time Control:** Ensures fast load transient response.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Pre-Biased Startup:** Prevents negative current during startup.  
- **Soft-Start & Soft-Stop:** Reduces inrush current and voltage spikes.  
- **Protections:** Overvoltage (OVP), undervoltage (UVP), and overcurrent (OCP) protection.  

This information is based solely on the manufacturer's datasheet and technical documentation.
