Description and Introduction

Mid Range Input (4.5V-28V) up to 1 MHz Frequency Synchronous Buck Controller, source/sink The TPS40071PWP 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 (adjustable)  
- **Switching Frequency:** 100kHz to 600kHz (adjustable)  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** HTSSOP-20 (PWP)  

### **Descriptions:**  
The TPS40071PWP is a high-performance, synchronous buck controller designed for DC-DC power conversion applications. It supports a wide input voltage range and provides efficient power conversion with adjustable output voltage. The device features a fixed-frequency PWM control scheme and is suitable for point-of-load (POL) power supplies in industrial, telecom, and computing systems.

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 28V operation.  
- **Adjustable Output Voltage:** Configurable from 0.7V to 5.5V.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size (100kHz to 600kHz).  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overcurrent Protection (OCP):** Enhances system reliability.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **100% Duty Cycle Capability:** Ensures operation even at low input voltages.  

This information is based on TI's official datasheet for the TPS40071PWP.
