DESCRIPTION
The SiC734CD9 is an integrated solution which contains two
PWM-optimized MOSFETs (high side and low side MOS-
FETs) and a driver IC. Integrating the driver allows better op-
timization of Power MOSFETs. This minimizes the losses
and provides better performance at higher frequency. The

SiC734CD9 is packed in Vishay Siliconix’s high performance
PowerPAK MLF 9 x 9 package. Compact co-packing of com-
ponents helps to reduce stray inductance, and hence in-
creases efficiency.
