Ballast Control IC for Compact Fluorescent Lamps

General 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.
