The OZ9938GN from O2Micro is a high-performance, cost-effective CCFL (Cold Cathode Fluorescent Lamp) controller. It is specifically designed for driving large-size Liquid Crystal Display (LCD) applications that require 2 to 6 CCFLs.
This controller converts unregulated DC voltages into nearly sinusoidal lamp voltage and current waveforms. It provides two drive signals for various power conversion topologies while maintaining high-efficiency operation. Key features include positive PWM dimming polarity, constant operating frequency, and the ability to drive lamps during ignition. The PWM controller also incorporates soft-start operation, current and voltage regulation, over-voltage and over-current protection.
Additional functionalities include user-defined ignition time and shutdown delay time, multiple dimming control modes (internal PWM, external PWM, or analog dimming), and built-in intelligence for CCFL ignition and normal operation. The OZ9938GN is housed in a SOIC 16-pin package, suitable for surface mounting.
This component is ideal for applications requiring precise control of CCFL backlighting in LCD panels, ensuring stable and efficient illumination.
