Description and Introduction

High Voltage 2.5 Amp Buck Regulator The LM5005MH is a high-voltage switching regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 6V to 75V  
- **Output Voltage Range:** Adjustable from 1.25V to 72V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (LM5005MH)  

### **Descriptions:**
The LM5005MH is a monolithic high-voltage switching regulator designed for step-down (buck) applications. It integrates a 75V N-channel MOSFET and provides a simple, efficient solution for converting high input voltages to lower regulated outputs. The device operates in a constant on-time (COT) control mode, ensuring stable performance across varying load conditions.

### **Features:**
- **Wide Input Voltage Range (6V–75V)**  
- **Integrated 75V N-Channel MOSFET**  
- **Adjustable Output Voltage (1.25V–72V)**  
- **Programmable Switching Frequency (Up to 1MHz)**  
- **Constant On-Time (COT) Control for Fast Transient Response**  
- **Internal Soft-Start for Controlled Startup**  
- **Thermal Shutdown Protection**  
- **Undervoltage Lockout (UVLO)**  
- **Low Quiescent Current (Typical 2.5mA)**  

This information is based on the manufacturer's datasheet for the LM5005MH.
