Ballast IC Targets CFL Designs

Taking a system-in-a-package approach, the FAN7710 debuts as the most highly integrated ballast IC on the market developed for compact fluorescent lamp (CFL) designs. The device combines one high-side 625V gate driver circuit, two 550V MOSFETs, a frequency control circuit, a shunt regulator, plus the added features of active ZVS control and an open lamp detection function into one 8-DIP package. For both linear fluorescent lamp and CFL applications, the FAN7711 integrates all but the two high-power MOSFETs found in the FAN7710 in a choice of 8-DIP and 8-SOP packages. Prices for the FAN7710 and FAN7711 are $1.51 and $1.25 each/1,000, respectively. FAIRCHILD SEMICONDUCTOR, San Jose, CA. (800) 341-0392.
