Fairchild Semiconductor is offering a CCFL backlight inverter drive IC for use in N-N half-bridge, push-pull, and P-N full-bridge LCD backlight inverter designs.

The FAN7316 and FAN7317 are designed to support a wide input voltage range, and include built-in open lamp protection (OLP) and open lamp regulation (OLR) circuit.

According to the supplier, this has the benefit of eliminating up to 30 external components in four lamp circuit inverter designs compared to similar devices.

These CCFL backlight inverter drive ICs also feature selectable dimming polarity and analogue and burst dimming function.

The input voltage ranges are, for the FAN7316, 4.5V to 24V, and, for the FAN7317, 6V to 25.5V.
