Description and Introduction

Dual-Synchronous, Step-Down Controller with Out-of-AudioT Operation and 100-mA LDOs 24-VQFN -40 to 85 The TPS51125RGET is a synchronous buck controller manufactured by Texas Instruments (TI). Here are the factual details from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable (250kHz to 700kHz)  
- **Output Current:** Up to 25A (with external FETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin VQFN (RGET)  

### **Descriptions:**  
The TPS51125RGET is a high-efficiency synchronous buck controller designed for DC-DC voltage regulation in applications such as notebooks, desktops, and embedded systems. It supports high-current outputs when paired with external power MOSFETs.
