FAN6751HLMY

Highly Integrated Green-Mode PWM Controller

Fairchild Semiconductor 

AN-6073

APPLICATION NOTE

Output Driver / Soft Driving

The FAN6751’s output stage is a fast totem-pole gate driver

capable of directly driving an external MOSFET. An

internal Zener diode clamps the driver voltage under 18V to

protect the MOSFET against over-voltage. By integrating

special circuits to control the slew rate of switch-on rising

time, the external resistor Rg may not be necessary to reduce

switching noise, improving EMI performance.
