The UBA2021 is an integrated circuit for electronically ballasted compact fluorescent
lamps and their derivatives operating with mains voltages up to 240 V (RMS). It provides
all the necessary functions for preheat, ignition and on-state operation of the lamp. In
addition to the control function, the IC provides level shift and drive functions for the two
discrete power MOSFETs, T1 and T2 (see
