UBA2016A/15/15A
600 V fluorescent lamp driver with PFC, linear dimming and
boost function
Rev. 3 — 16 November 2011
Product data sheet
1. General description
The UBA2016A/15/15A are high voltage Integrated Circuits (IC) intended to drive
fluorescent lamps with filaments such as Tube Lamps (TL) and Compact Fluorescent
Lamps (CFL) in general lighting applications. The IC comprises a fluorescent lamp control
module, half-bridge driver, built-in critical conduction mode Power Factor Correction
(PFC) controller/driver and several protection mechanisms. The IC drives fluorescent
lamp(s) using a half-bridge circuit made of two MOSFETs with a supply voltage of up to
600 V.
The UBA2016A/15/15A are designed to be supplied by a start-up bleeder resistor and a
dV/dt supply from the half-bridge circuit, or any other auxiliary supply derived from the
half-bridge or the PFC. The supply current of the IC is low. An internal clamp limits the
supply voltage.
2. Features and benefits
Power factor correction features:
Integrated 4-pin critical conduction mode PFC controller/driver
Open and short pin-short protection on PFC feedback pin
Overcurrent protection
Overvoltage protection
Half-bridge driver features:
Integrated level-shifter for the high-side driver of the half-bridge
Integrated bootstrap diode for the high-side driver supply of the half-bridge
Independent non-overlap time
Fluorescent lamp controller features:
Linear dimming (UBA2016A and UBA2015A only)
EOL (End-Of-Life) detection (both symmetrical and asymmetrical)
Adjustable preheat time
Adjustable preheat current
Adjustable fixed frequency preheat (UBA2015 and UBA2015A only)
Lamp ignition failure detection
Ignition detection of all lamps at multiple lamps with separate resonant tanks
Second ignition attempt if first failed
Constant output power independent of mains voltage variations
Automatic restart after changing lamps
Adjustable lamp current boost at start-up (UBA2016A only)
Lamp current control
