OZ9938GN Integrated Circuit

OZ9938GN IC

LCDM Inverter Controller

16-pin SOIC

GENERAL DESCRIPTION
The OZ9938 is a high performance, cost-effective CCFL (Cold Cathode Fluorescent Lamp) controller designed for driving large-size Liquid Crystal Display (LCD) applications requiring 2 to 6 CCFLs.
The controller converts unregulated DC voltages into a nearly sinusoidal lamp voltage and current waveforms.
The OZ9938 provides two drive signals for most power conversion topologies while maintaining high-efficiency operation. The PWM controller provides a soft-start operation, current and voltage regulation, over-voltage and over-current protection, high drive capability and multiple dimming functions (internal PWM or external PWM or analog dimming functions).
