Description
OZ9938 Change Summary CHANGES No.1.2.Applicable Section Electrical Characteristics Throughout datasheet .
Features
* Positive PWM dimming polarity Constant operating frequency Drives positive/negative-impedance lamps during ignition High drive current for external MOSFETs User-defined ignition time and shutdown delay time Multiple mode dimming control Built-in intelligence for ignition and normal operation of CCFLApplications
* 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 operatOZ9938 Distributors
