New 2W DC-DC converters designed to power SiC MOSFETs

To meet the tough requirements of next-generation MOSFETs, RECOM has introduced two new 2W DC-DC converter series especially 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 3kVDC, 4kVDC, 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 RxxP22005D and RKZ-xx2005D series are available with input voltages of 5V, 12V, 15V or 24V and feature asymmetric outputs of +20V and -5V to efficiently and effectively switch the SiC MOSFET. The converters come fully equipped with an ultra-low parasitic capacitance and power sharing capabilities, and they are all fully compliant to UL-60950-1, RoHS2, and REACH, says the company.
