FAN7316 and FAN7317

Fairchild Semiconductor has introduced what it claims as the industry's most integrated CCFL backlight inverter drive ICs that promise space and cost savings, superior 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) and open lamp regulation (OLR) circuit, eliminate up to 30 external components in four lamp circuit inverter designs compared to similar devices on the market. These highly integrated CCFL backlight inverter drive ICs also feature selectable dimming polarity and analogue and burst dimming functions, which simplify design and speed time-to-market.

"Fairchild's FAN7316 and FAN7317 offer the industry's most comprehensive protection functions resulting in superior system reliability. By reducing the number of components, these devices specifically address the ever-growing need to reduce overall system cost in LCD designs," said Jay Lee, director of Fairchild's lighting product line.

The FAN7316 and FAN7317 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 Pb-free terminals and have been characterised for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/Jedec standard J-STD-020.

In 1,000 quantities, the FAN7316 is priced at Rs.58.43 ($1.48) and the FAN7317 at Rs.16.19 ($1.55). Both devices are already available, with delivery at 12 week ARO.
