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).
The control logic provides a regulated ignition
voltage and appropriate protection features for
over-voltage or over-current conditions.
The OZ9938 offers a high level of integration,
while maintaining flexibility and high-efficiency
operation that reduces external component
heating, resulting in higher reliability and longer
CCFL life. The proprietary design technique
provides a simple, low-cost system solution.
