NEW PRODUCT NEWSedited by Rick Prescott

New ProductsLCD Backlight Driver

The Model LS650 is the latest addition to a popular line of ultra-compact CCFT (cold-cathode fluorescent tube) inverters for brightness control in LCD backlighting applications. Especially recommended for use with the NEC 6.5ý TFT display, the deviceýs rigid construction and compact, low-profile design (105 ý 25 ý 10 mm) helps manufacturers of industrial instruments and test and measurement equipment meet continuing design miniaturization requirements. The deviceýs single transformer and dual output capability also benefits OEMs by keeping cost down through reduced onboard component counts.

The CCFT inverter provides an input range of 11.4ý12.6 VDC (a 5-V input model is also available) and a total output of 4 W for two lamps. The easy-to-use brightness control function permits wide dimming (20ýl00%) adjustment by applying DC bias voltage (1.5ýl .9 V) or by means of a 0 to 10-kW variable resistor.

The LS650 is priced at $15 in OEM quantities.
