UBA2013/L3
HB driver IC with PFC for fluorescent rings
Rev. 00.01 — 23 February 2007 Preliminary data sheet
1. General 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.
2. Features
2.1 Half bridge
Suitable for cold and warm ignition Adjustable preheat time Adjustable ignition voltage Integrated bootstrap function Protection for lamp failure and end-of-life Adjustable preheat current Single ignition attempt Automatic restart after relamping Protection for capacitive mode
2.2 PFC
Three pin PFC controller using TON control Critical mode operation Overvoltage/overcurrent protection
3. Applications
The UBA2013/L3 can provide the drive and control function for a wide range of half bridge based ballast applications at different mains voltages.
