Description and Introduction

Dual-Synchronous, Step-Down Controller with Out-of-Audio Operation and 100-mA LDOs 24-VQFN -40 to 85 The TPS51125ARGER is a synchronous buck controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on 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 1.2MHz (adjustable)  
- **Output Current:** Up to 25A (with external FETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin VQFN (4mm x 4mm)  

### **Descriptions:**  
The TPS51125ARGER is a high-performance synchronous buck controller designed for high-current, low-voltage applications. It supports a wide input voltage range and provides precise output voltage regulation. It is commonly used in point-of-load (POL) power supplies, networking equipment, and industrial applications.  

### **Features:**  
- **Adjustable Output Voltage:** Supports 0.76V to 5.5V via external resistor divider.  
- **Wide Input Voltage Range:** 4.5V to 28V.  
- **Adjustable Switching Frequency:** 300kHz to 1.2MHz for optimization of efficiency and component size.  
- **High Efficiency:** Uses synchronous rectification for improved power conversion.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Soft-Start & Overcurrent Protection:** Ensures safe operation.  
- **Thermal Shutdown:** Protects against overheating.  

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