Datasheet Details

Part number:

OZ9938

Manufacturer:

O2 Micro

File Size:

Description:

LCDM Inverter Controller

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 CCFL

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 operat
