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
