FEATURES
• Constant operating frequency
• Drives positive/negative-impedance lamps
during ignition
• High drive current for external MOSFETs
• User-defined ignition time and shutdown
delay time
• Built-in intelligence for ignition and normal
operation of CCFLs
• Built-in open-lamp protection and overvoltage
protection for backlight system
• Optimized soft-start function
GENERAL DESCRIPTION
ta9687 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 ta9687 supports full-bridge power conversion
topologies while maintaining high-efficiency
operation. The controller provides a soft-start
operation, current and voltage regulation, overvoltage
and over-current protection, high drive
capability.
The control logic provides a regulated ignition
voltage and appropriate protection features for
over-voltage or over-current conditions.
The ta9687 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.
