Dimmable controller IC for CFL
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
The UBA20270 is a high voltage IC, to be used with two external NMOS power FETs, intended to control high power self ballasted dimmable Compact Fluorescent Lamps (CFL). The UBA20270 has advanced features for dimming and a lamp current controlled boost feature for boosting cold (amalgam) CFL lamps. The controller contains a half-bridge drive function, including a high voltage level-shift circuit with integrated bootstrap diode, an oscillator function, a current control function both for preheat and burn, timer function and protection circuits. The UBA20270 is supplied via a high-efficient dV/dt supply circuit.
