„ Compact Fluorescent Lamp Ballast 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 a 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.  8-DIP
