Description and Introduction

High Voltage (80V) Step Down Switching Regulator The LM5007 is a high-voltage switching regulator manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 8V to 75V  
- **Output Voltage Range:** Adjustable from 1.25V to 72V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The LM5007 is a monolithic high-voltage buck switching regulator designed for step-down DC-DC conversion. 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 (8V–75V)**  
- **Integrated High-Side MOSFET**  
- **Adjustable Output Voltage**  
- **Adjustable Switching Frequency (Up to 1MHz)**  
- **Constant On-Time (COT) Control**  
- **Thermal Shutdown Protection**  
- **Undervoltage Lockout (UVLO)**  
- **Low Quiescent Current (3.5mA typical)**  
- **Cycle-by-Cycle Current Limiting**  

This information is based solely on the manufacturer's datasheet for the LM5007.
