UBA20261/2 600 V and 350 V power IC for step dimmable CFLs Rev. 2 — 10 October 2011 Product data sheet 1. General description The UBA20261/2 are high-voltage power integrated circuits designed to drive and control high powered self-ballasted Compact Fluorescent Lamp (CFL) lighting applications operating at mains supply voltages of 120 V or 230 V. The IC includes a half-bridge power circuit consisting of two NMOST power MOSFETs, an advanced feature for step dimming and a lamp current controlled boost feature for boosting cold (amalgam) CFLs. The controller contains a CFL half-bridge drive function, a high-voltage level-shift circuit with integrated bootstrap diode, an oscillator function, a current control function for preheat and burn, a timer function and protection circuits.
