ZXGD3104EV2 USER GUIDE
Introduction
The purpose of this board is to demonstrate the driving of a synchronous MOSFET as a Schottky
replacement in isolated power supplies. The circuit is suitable for use in AC/DC Flyback converters.
End applications include external power adaptors for laptops greater than 90W, and LED monitors.
When used to drive a low on-resistance MOSFET, the board increases power efficiency whilst still
maintaining simplicity of design.
Performance
• Recommended supply voltage VIN: 19V
• Gate voltage clamped to 12V maximum
• Ideal for Quasi Resonant operation
• Switching frequency up to 250KHz
