Description
The FAN7710, developed using Fairchild’s unique high-
voltage process and system-in-package (SiP) concept, is
a ballast control integrated circuit (IC) for a compact
fluorescent lamp (CFL). The FAN7710 controls internal
high-voltage stress and delivers 20W to the lamp at
310VDC voltage. FAN7710 incorporates a preheating /
ignition function, controlled by an user-selected external
capacitor, to increase lamp life. The FAN7710 detects
switch operation from after ignition-mode through an
internal active Zero-Voltage Switching (ZVS) control
circuit. This control scheme enables the FAN7710 to
detect an open-lamp condition, without the expense of
external circuitry, and prevents stress on MOSFETs. The
high-side driver built into the FAN7710 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. TA=25°C unless otherwise specified.
