Description and Introduction

Quad Output (3 Buck, 1 Boost) High Efficiency DC/DC Controller for Notebook PC Power The TPS5140PAGR is a synchronous buck controller manufactured by Texas Instruments (TI). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.9V to 5.5V (adjustable)  
- **Switching Frequency:** 300kHz (fixed)  
- **Maximum Output Current:** Up to 20A (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-pin TQFP (PAGR)  

### **Descriptions:**  
The TPS5140PAGR is a high-efficiency, synchronous step-down (buck) DC-DC controller designed for high-current applications. It integrates MOSFET drivers and supports a wide input voltage range, making it suitable for point-of-load (POL) power supplies in computing, networking, and industrial systems.  

### **Features:**  
- **Voltage Mode Control:** Provides stable and accurate output regulation.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Programmable Soft-Start:** Prevents inrush current during startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load currents.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Power Good (PG) Output:** Monitors output voltage status.  
- **Adjustable Output Voltage:** Set via external resistor divider.
