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.
