CCFL backlight inverter drive ICs address cost, design issues

Fairchild Semiconductor introduces what it claims as the industry's most integrated CCFL backlight inverter drive ICs for LCD backlight systems. The FAN7316 and FAN7317 devices are said to provide space and cost savings, excellent system reliability and simplified design for N-N half-bridge, push-pull, and P-N full-bridge LCD backlight inverter designs.

The FAN7316 and FAN7317, featuring a wide input voltage range and built-in open lamp protection (OLP), eliminate up to 30 external components in four lamp circuit inverter designs compared to similar devices on the market, said Fairchild. The FAN7317 also features an open lamp regulation (OLR) circuit. These highly integrated CCFL backlight inverter drive ICs feature selectable dimming polarity and analog and burst dimming functions, which simplify design and speed time-to-market.

Protection features include built-in OLP circuit, open lamp regulation, short circuit protection (SCP), thermal shutdown (TSD), soft-start and arc protection.

The FAN7316 and FAN7317 devices are available in a 20-pin SOIC Pb-free package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C. Both use lead-free terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. The devices are RoHS compliant. Price is $1.48 each for the FAN7316 and $1.55 each for the FAN7317 in quantities of 1,000.
