Description
FAN7710V and FAN7710VL, developed using Fairchild’s
unique high-voltage process and system-in-package
(SiP) concept, are ballast control integrated circuits (ICs)
for compact fluorescent lamps (CFL). FAN7710V/VL
incorporate a preheating / ignition function, controlled by
a user-selected external capacitor, to increase lamp life.
The FAN7710V detects switch operation from after
ignition mode through an internal active Zero-Voltage
Switching (ZVS) control circuit (FAN7710VL does not).
This control scheme enables the FAN7710V to detect an
open-lamp condition without the expense of external
circuitry and prevents stress on MOSFETs. The high-side
driver built into the FAN7710V/VL has a common-mode
noise cancellation circuit that provides robust operation
against high-dv/dt noise intrusion.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In
addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. T
