UBA2013L
description
The UBA2013/L3 is a high voltage IC intended to drive and control fluorescent lamps. The IC can handle both cold and warm ignition of the lamp. It contains a TON-controlled PFC function, a half bridge controller circuit with level shifter and an internal bootstrap diode to drive an external half bridge. UBA2013/L3 also offers a functionality to properly handle fault conditions such as capacitive mode switching, end-of-lamp-life and overcurrent. UBA2013/L3 is designed for wide-input mains voltage (120 V
- 277 V) applications.
