Description and Introduction

High Efficiency, Mid-Range Input, Synchronous Buck Controller with Voltage Feed Forward 16-HTSSOP -40 to 85 The TPS40077PWPR 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:** 300kHz to 1MHz (adjustable)  
- **Maximum Output Current:** Configurable with external MOSFETs  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
The TPS40077PWPR is a high-performance, wide-input voltage synchronous buck controller designed for DC-DC power conversion. It supports step-down voltage regulation with high efficiency and flexible design options.  

### **Features:**  
- **Adjustable Output Voltage:** Uses an external resistor divider.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Precision Reference Voltage:** 0.7V ±1% for accurate regulation.  
- **Soft-Start Control:** Reduces inrush current during startup.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Overcurrent Protection:** Uses external MOSFET RDS(on) sensing.  
- **Thermal Shutdown:** Protects against overheating.  

This controller is commonly used in telecom, industrial, and computing applications requiring efficient power conversion.
