Description and Introduction

6-100V Wide Vin, Current Mode Synchronous Buck Controller 20-HTSSOP -40 to 150 The LM5116MHX is a synchronous buck controller manufactured by Texas Instruments (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 75V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable from 50kHz to 1MHz  
- **Maximum Duty Cycle:** 95%  
- **Driver Output Current:** 2A (source), 3A (sink)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-Pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
The LM5116MHX is a high-voltage buck controller designed for regulating low-voltage, high-current outputs from high-voltage inputs. It integrates high-side and low-side gate drivers, reducing external component count. The controller supports both synchronous and non-synchronous operation and includes features for robust power supply design.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 75V operation.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Precision Reference:** 0.8V ±1% voltage reference for accurate regulation.  
- **Integrated Gate Drivers:** Reduces external components.  
- **Current Mode Control:** Enhances transient response and simplifies compensation.  
- **Programmable Soft-Start:** Prevents inrush current issues.  
- **Protection Features:** Includes UVLO, thermal shutdown, and cycle-by-cycle current limiting.  
- **Synchronous Rectification:** Improves efficiency by replacing the freewheeling diode with a MOSFET.  

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