DESCRIPTION

· High-voltage IC for driving fluorescent lamps like TL and CFL in general lighting.
· Includes fluorescent lamp control module, half-bridge driver, and protection mechanisms.
· Operates with a half-bridge circuit using two MOSFETs, supporting up to 600 V.
· Powered by a start-up bleeder resistor and dV/dt supply from the half-bridge.
· Features low supply current and an internal clamp for voltage limitation.

FEATURES

· Half-bridge driver with integrated level-shifter and bootstrap diode.
· Independent non-overlap time for efficient operation.
· Fluorescent lamp controller with linear dimming (UBA2017A only).
· EOL detection, adjustable preheat time, and current.
· Lamp ignition failure detection and second ignition attempt.
· Constant output power and automatic restart after lamp change.
· Comprehensive protection against hard switching, overcurrent, overvoltage, and temperature.

APPLICATIONS

· Suitable for general lighting applications using fluorescent lamps.
· Ideal for Tube Lamps (TL) and Compact Fluorescent Lamps (CFL).
