Abstract :
A ballast IC, which has a system-in-package (SiP) concept is designed using Fairchild´s high voltage BCDMOS processes. The ballast control IC, which includes 625V high-side gate driver circuit and two 550V MOSFETs are integrated in low cost 8DIP package. The proposed IC provides lamp preheating and ignition functions to increase the lamp lifetime. Also, to increase the inverter efficiency, an active ZVS operation is incorporated. The proposed IC can drive up to 20W CFL with 90% efficiency at 310V DC link voltage
