UBA2016A/15/15A:600 V fluorescent lamp driver with PFC, linear dimming and boost function 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. UBA2016A/15/15A主要特性和優勢: 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 fat 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 Enable input (UBA2015 and UBA2015A only) Protection Hard switching/capacitive mode protection Half-bridge overcurrent (coil saturation) protection Lamp overvoltage (lamp removal) protection Temperature protection UBA2016A/15/15A應用: Intended for fluorescent lamp ballasts with either a dimmable (UBA2016A and UBA2015A) or a fixed (UBA2015) output and PFC for AC mains voltages of up to 390 V.
