Description and Introduction

36V, 2A PowerWise? Adjustable Frequency Synchronous Buck Regulator The LM20242MH is a synchronous buck regulator manufactured by National Semiconductor (NS). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 42V  
- **Output Voltage Range:** 0.8V to 36V (adjustable via external resistors)  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 500kHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
The LM20242MH is a high-efficiency, step-down DC-DC converter designed for industrial, automotive, and telecom applications. It integrates a high-side and low-side MOSFET for synchronous rectification, reducing power loss and improving efficiency. The regulator supports adjustable output voltage and frequency, along with protection features like thermal shutdown and current limiting.

### **Features:**  
- **Wide Input Voltage Range (4.5V to 42V)**  
- **Integrated High-Side and Low-Side MOSFETs**  
- **Adjustable Switching Frequency (300kHz to 1MHz)**  
- **Programmable Soft-Start**  
- **Cycle-by-Cycle Current Limiting**  
- **Thermal Shutdown Protection**  
- **PowerPAD™ Package for Enhanced Thermal Performance**  
- **Synchronization Capability with External Clock**  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
