FAN7710 Overview
The FAN7710, developed using Fairchild’s unique highvoltage process and system-in-package (SiP) concept, is a ballast control integrated circuit (IC) for a pact 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.
