FAN7710 Ballast Control circuit design

Posted on Feb 7, 2014

Using the FAN7710 Ballast Control IC for Compact Fluorescent Lamps developed using Fairchild`s unique highvoltage process and system-in-package (SiP) concept can be designed a very simple low cost fluorescent lamp driver electronic project. The FAN7710 ballast control controls internal high-voltage stress and delivers 20W to the lamp at 320VDC vo

ltage. FAN7710 ballast control 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. The AC line input voltage (230 VAC 50 Hz) is rectified to provide a bus voltage of approximately 320 volts DC. Startup resistor R1 supplies initial power to the FAN7710 IC. The IC begins to oscillate and the charge pump circuit consisting of C2, D2 and D7 supplies the current to the VDD pin, which gets regulated through the internal 15-V shunt regulator.
