Description and Introduction

High Voltage 2.5 Amp Buck Regulator The LM5005MHX is a high-voltage switching regulator manufactured by National Semiconductor (NS).  

**Specifications:**  
- **Input Voltage Range:** 6V to 75V  
- **Output Voltage:** Adjustable from 1.225V to 70V  
- **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 (exposed pad for thermal dissipation)  

**Descriptions:**  
The LM5005MHX is a step-down (buck) switching regulator designed for high-voltage applications. It integrates a high-side N-channel MOSFET and features a constant on-time (COT) control scheme for fast transient response.  

**Features:**  
- Wide input voltage range (6V to 75V)  
- Adjustable output voltage  
- Internal high-side MOSFET (500mA current limit)  
- Adjustable switching frequency (up to 1MHz)  
- Thermal shutdown protection  
- Under-voltage lockout (UVLO)  
- Low shutdown current (<10µA)  
- Exposed thermal pad for improved heat dissipation  

This regulator is commonly used in industrial, automotive, and telecom applications requiring efficient power conversion from high-voltage sources.
