UBA2017/UBA2017A
600 V fluorescent lamp driver with linear dimming function
Rev. 2 — 15 May 2012
Product data sheet
1. General description
The UBA2017/UBA2017A 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 and several protection mechanisms. The IC drives fluorescent
lamps using a half-bridge circuit made of two MOSFETs with a supply voltage of up to
600 V.
The UBA2017/UBA2017A are 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. The
supply current of the IC is low. An internal clamp limits the supply voltage.
2. Features and benefits
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 (UBA2017A only)
EOL (End-Of-Life) detection (both symmetrical and asymmetrical)
Adjustable preheat time
Adjustable preheat current
Adjustable fixed frequency preheat
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
Lamp current control
Enable input
Protection
Hard switching/capacitive mode protection
Half-bridge overcurrent (coil saturation) protection
Lamp overvoltage (lamp removal) protection
Temperature protection
