CCFL Backlight Inverter Drive IC is Tightly Integrated
Fairchild Semiconductor's FAN7316 and FAN7317 are CCFL backlight inverter drive ICs for N-N half-bridge, push-pull, and P-N full-bridge LCD designs. A wide input voltage range, built-in open lamp protection, and open lamp regulation eliminate up to 30 external components in traditional four-lamp circuit inverter designs. The FAN7316 runs on 4.5V to 24V, and the FAN7317 uses 6V to 25.5V. Other features are short-circuit protection, thermal shutdown, soft-start and arc protection, selectable dimming polarity, analog and burst dimming mode, and PWM dimming by an external pulse signal. Pricing is $1.48 for the 7316 and $1.55 for the 7317.
