UBA2017 - NXP

UBA2017 600V fluorescent lamp driver

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-b.

Features

 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.
