DESCRIPTION
D
This new series of low charge Power MOSFETs achieve
signiticantly lower gate charge over conventional MOSFETs.
Utilizing the new LCDMOS technology, the device
improvements are achieved without added product cost,
allowing for reduced gate drive requirements and total
system savings. In addition, reduced switching losses and
improved efficiency are achievable in a variety of high
frequency applications. Frequencies of a few MHz at high
current are possible using the new low charge MOSFETs.
