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 UBA...
