General description
The UBA20260 is a high-
voltage integrated circuit designed to control high power self-ballasted Compact Fluorescent Lamp (CFL) lighting applications.
The UBA20260 is a controller circuit with advanced features for step dimming and a lamp current controlled boost feature for boosting cold (amalgam) CFLs.
The controller contains a half-bridge drive function for CFLs, 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.
The UBA20260 is supplied using t...
