Description and Introduction

DDR1, DDR2, DDR3 Switcher and LDO 20-HTSSOP -40 to 85 The TPS51116PWPG4 is a synchronous buck controller manufactured by Texas Instruments (TI).  

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

### **Descriptions:**  
The TPS51116PWPG4 is a high-efficiency synchronous buck controller designed for notebook and desktop power applications. It integrates gate drivers and supports high-current output with external MOSFETs. It features adaptive on-time control for fast transient response and supports D-CAP™ mode for simplified compensation.  

### **Features:**  
- **D-CAP™ Mode Control:** Reduces external components and simplifies design.  
- **Adaptive On-Time Control:** Ensures fast transient response.  
- **Integrated Gate Drivers:** Supports N-channel MOSFETs.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Adjustable Soft Start:** Prevents inrush current.  
- **Overcurrent Protection (OCP) & Overvoltage Protection (OVP):** Enhances system reliability.  
- **Thermal Shutdown:** Protects against overheating.  

This controller is commonly used in notebook PCs, desktops, and other high-performance power supply applications.
