Description and Introduction

Single Phase PWM Controller with Light-Load Efficiency Optimization 16-QFN -40 to 85 The TPS53211RGTR is a synchronous buck controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** 0.7V to 5.5V  
- **Switching Frequency:** Adjustable from 200kHz to 1MHz  
- **Maximum Output Current:** Supports up to 25A (with external MOSFETs)  
- **Control Method:** Voltage Mode Control  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin VQFN (RGTR)  

### **Descriptions:**  
The TPS53211RGTR is a high-performance synchronous buck controller designed for high-current, low-voltage applications. It integrates a gate driver and supports external MOSFETs to achieve high efficiency and precise voltage regulation.  

### **Features:**  
- **Adjustable Soft-Start** – Reduces inrush current during startup.  
- **Precision Reference Voltage** – 0.7V ±1% accuracy.  
- **Power Good Indicator** – Monitors output voltage status.  
- **Overcurrent Protection (OCP)** – Prevents damage from excessive current.  
- **Thermal Shutdown** – Protects the device from overheating.  
- **Adjustable Switching Frequency** – Allows optimization for efficiency or size.  
- **Synchronization Capability** – Can sync to an external clock.  

This device is commonly used in point-of-load (POL) regulators, telecom, networking, and industrial applications.
