UBA20270 600 V Driver IC for dimmable compact fluorescent lamps Rev. 2 — 8 September 2011 Product data sheet 1. General description The UBA20270 is a high-voltage power IC intended to control higher powered self ballasted Compact Fluorescent Lamp (CFL) lighting applications. The UBA20270 is a controller circuit with advanced features for dimming and has a lamp current controlled boost feature for boosting cold (amalgam) CFLs. The controller contains a half-bridge drive function for CFL, a high-voltage level-shift circuit with integrated bootstrap diode. In addition, the controller contains an oscillator function, a current control function both for preheat and burn, a timer function and protection circuits.
