Overview
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.
The UBA20270 is supplied via a dV/dt current charge supply circuit from the half-bridge circuit.
Remark: Mains voltages noted are AC.
