FAN7711 DIP-8

Description
The FAN7711, developed with Fairchild’s unique highvoltage process, is a ballast control integrated circuit (IC)
for a fluorescent lamp. FAN7711 incorporates a preheating
/ ignition function, controlled by an user-selected external
capacitor, to increase lamp life. The FAN7711 detects
switch operation from after ignition mode through an
internal active Zero-Voltage Switching (ZVS) control
circuit. This control scheme enables the FAN7711 to
detect an open-lamp condition, without the expense of
external circuitry, and prevents stress on MOSFETs. The
high-side driver built into the FAN7711 has a commonmode noise cancellation circuit that provides robust
operation against high-dv/dt noise intrusion.
