Description
FAN7710V developed using Fairchild’s high-voltage
process and system-in-package (SiP) concept, are
ballast-control integrated circuits (ICs) for compact
fluorescent lamps (CFL). FAN7710V incorporates a
preheating / ignition function, controlled by a user-
selected external capacitor, to increase lamp life. The
FAN7710V detects switch operation after ignition mode
through an internal active Zero-Voltage Switching (ZVS)
control circuit. This control scheme enables the
FAN7710V to detect an open-lamp condition, without the
expense of external circuitry, and prevents stress on the
MOSFETs. The high-side driver in the FAN7710V has a
common-mode noise cancellation circuit that provides
robust operation against high-dv/dt noise intrusion.
