UBA2015AP: Dimmable HF-TL controller IC with PFC ARCHIVED

Overview

Archived content is no longer updated and is made available for historical reference only.

The UBA2015AP is a high voltage Integrated Circuit (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 UBA2015AP is 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.
