To meet the tough requirements of next-gen MOSFETs, RECOM has introduced two 2W DC/DC converter series designed to power SiC MOSFETs. One of the challenges of driving SiC MOSFETs is the high frequency and high voltage at which they are switched. High potentials between the control and power side of a SiC MOSFET application can wear down isolation barriers, eventually causing them to fail.

The RxxP22005D and RKZ-xx2005D series come with 3, 4k and even 5.2kVDC isolation to ensure that the isolation barrier stands up to even the harshest tests. Switching SiC MOSFETs requires turn-on and turn-off voltages which are not common for other IGBT or MOSFET applications. The converter series are available with input voltages of 5, 12, 15 or 24V and feature asymmetric outputs of +20 and -5V to efficiently and effectively switch the SiC MOSFET.

These converters come fully equipped with an ultra-low parasitic capacitance and power sharing capabilities, as well as all being fully compliant to UL-60950-1, RoHS2 and REACH. High operating temperatures coupled with high-frequency switching make the SiC MOSFET harsh for power supplies. RECOM only uses high quality name-brand components in its state-of-the art design to offer a three year warranty, even in harsh environments.
