Description and Introduction

High-Voltage Current-Mode PWM Controller The part HV9120NG is manufactured by SUPERTEX. It is a high-voltage, low-side N-channel MOSFET driver designed for applications requiring high voltage switching. Key specifications include:

- **Output Voltage**: Up to 600V  
- **Peak Output Current**: 1.5A  
- **Supply Voltage Range**: 10V to 20V  
- **Propagation Delay**: 30ns (typical)  
- **Rise/Fall Time**: 15ns (typical)  
- **Operating Temperature Range**: -40°C to +125°C  
- **Package**: 8-pin DIP or SOIC  

The HV9120NG is commonly used in power supplies, inverters, and other high-voltage switching applications.  

(Note: Always verify specifications with the latest datasheet from the manufacturer.)
