MOSFETs address LCD backlighting

21st July 2009

Diodes Incorporated has extended its MOSFET offering with the introduction of 15 devices tailored to the needs of LCD TV and monitor backlighting. Provided in industry standard TO252 and SO8 packaging, the MOSFETs deliver the high power handling and fast switching required by high efficiency CCFL drive architectures.
The 30V rated, SO8 packaged dual n-channel DMN3024LSD suits push-pull inverters and offers a space saving advantage over discrete component alternatives. In full and half bridge topologies needing complementary pairs, the DMC3028LSD provides an integrated high performance n- and p-channel MOSFET combination.

For backlighting applications with multiple lamps, the extended TO252 MOSFET product family meets the higher power handling requirements with optimised on-resistance and gate charge performance. 9 new n-channel and 3 new p-channel parts cover the drain source voltage range from 20V through to 60V.
