Description and Introduction

4A, PowerWise? Adjustable Frequency Synchronous Buck Regulator The part **LM20144MH** is manufactured by **NS (National Semiconductor)**.

### **Specifications:**
- **Type:** Synchronous Buck Regulator  
- **Input Voltage Range:** 4.5V to 42V  
- **Output Voltage Range:** 0.8V to 85% of VIN  
- **Output Current:** Up to 4A  
- **Switching Frequency:** Adjustable (300kHz to 2MHz)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-Pin HTSSOP  

### **Descriptions:**
The **LM20144MH** is a high-efficiency, synchronous step-down DC-DC converter designed for a wide input voltage range. It integrates high-side and low-side MOSFETs, reducing external component count. It supports adjustable frequency operation and includes features like soft-start, thermal shutdown, and cycle-by-cycle current limiting.

### **Features:**
- **Wide Input Voltage Range (4.5V to 42V)**  
- **Integrated Power MOSFETs**  
- **Adjustable Switching Frequency (300kHz to 2MHz)**  
- **Programmable Soft-Start**  
- **Cycle-by-Cycle Current Limiting**  
- **Thermal Shutdown Protection**  
- **Synchronizable to External Clock**  
- **Low Quiescent Current in Standby Mode**
