Description and Introduction

6-100V Wide Vin, Current Mode Synchronous Buck Controller 20-HTSSOP -40 to 150 The LM5116MH is a synchronous buck controller manufactured by Texas Instruments (NS). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 75V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable from 50kHz to 1MHz  
- **Driver Output Current:** 3A peak source/sink  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
The LM5116MH is a high-voltage buck controller designed for regulating low-voltage power supplies from high input voltages. It integrates a high-side and low-side gate driver, enabling efficient synchronous rectification. The controller supports adaptive dead-time control and programmable soft-start.

### **Features:**  
- **Wide Input Voltage Range (4.5V to 75V)**  
- **Adjustable Output Voltage (0.8V and above)**  
- **Programmable Switching Frequency (50kHz to 1MHz)**  
- **Adaptive Dead-Time Control for Efficiency Optimization**  
- **Integrated High-Current Gate Drivers (3A peak)**  
- **Programmable Soft-Start**  
- **Cycle-by-Cycle Current Limiting**  
- **Thermal Shutdown Protection**  
- **PowerPAD™ Package for Enhanced Thermal Performance**
