Description and Introduction

Mid Range Input (4.5V-28V) up to 1 MHz Frequency Synchronous Buck Controller, source only The TPS40070PWP is a synchronous buck controller manufactured by Texas Instruments (TI). Here 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 Output Current:** Up to 20A (with external FETs)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** HTSSOP-20 (PWP)  

### **Descriptions:**  
The TPS40070PWP is a high-performance, wide-input-voltage synchronous buck controller designed for DC/DC converter applications. It supports step-down voltage conversion with high efficiency and integrates features for power management in industrial, telecom, and computing systems.

### **Features:**  
- **Adjustable Output Voltage:** Supports external resistor divider for flexibility.  
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  
- **Programmable Soft-Start:** Prevents inrush current during startup.  
- **Overcurrent Protection (OCP):** Uses external FET RDS(on) sensing.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Thermal Shutdown:** Protects the device from overheating.  

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