Description and Introduction

Dual Synchronous Step-Down Controller with 5-V and 3.3-V LDOs 20-WQFN -40 to 85 The TPS51225CRUKR is a synchronous buck controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.7V to 5.5V  
- **Switching Frequency:** Adjustable from 200kHz to 1MHz  
- **Output Current:** Supports up to 25A (with external FETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin VQFN (3.5mm x 4.5mm)  

### **Descriptions:**  
The TPS51225CRUKR is a high-performance synchronous buck controller designed for point-of-load (POL) applications. It provides precise voltage regulation for powering processors, FPGAs, and other high-current loads. The device supports adaptive on-time control for fast transient response and integrates features for power sequencing and protection.  

### **Features:**  
- **Adaptive On-Time Control** for fast load transient response  
- **Adjustable Soft-Start** for controlled startup  
- **Power Good Indicator** for system monitoring  
- **Pre-Bias Startup** capability  
- **Overcurrent Protection (OCP)** and **Overvoltage Protection (OVP)**  
- **Thermal Shutdown** for safety  
- **Supports D-CAP3™ Mode** for stable operation with low ESR output capacitors  

This information is strictly based on TI's official documentation for the TPS51225CRUKR.
