The 8mAD series of dc/ac inverters from Endicott Research Group are designed to power larger LCD panels that use two 4-W cold-cathode fluorescent lamps (CCFL) for backlighting, Two versions are offered, to allow operation from either a 5 VDC or a 12 VDC source, and both work with 260- and 300-mm diagonal screens. You can dim the backlight intensity down to 5% of maximum value, using an external analog control signal or pulse-width signal source. The 8-mm high inverters are US$10 in production quantities.
