IC801 TA9687GN
TA
9687 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
TA
9687 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
TA
9687 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.
