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.
