7. Functional description
7.1 Introduction
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 Figure 7).
