Highly Integrated ¡°System-In-A-Package¡° Ballast IC for Compact Fluorescent Lamps

Fairchild Semiconductor introduces Two ICs for CFL designs. The FAN7710 is a highly integrated ballast IC offering a ¡°system-in-a-package¡± approach, it optimizes performance while simplifying design and overcoming the space limitations of CFL lighting applications. The device combines one high-side 625V gate driver circuit, two 550V MOSFETs, a frequency control circuit and a shunt regulator ¨C¨C plus active ZVS control and an open lamp detection function ¨C¨C into one ultra-compact 8-DIP package. Its high functionality and built-in protection features save board space, reduce power dissipation and result in excellent temperature characteristics and enhanced reliability in end systems. The FAN7711 for linear fluorescent lamp (LFL) designs as well as CFL applications. This ballast IC integrates all but the two high-power MOSFETs offered by the FAN7710 to make it better suited to LFL designs. The FAN7711 is available in both 8-DIP and 8-SOP packages.
