DC/DC converters are optimised for SiC applications
6 October 2016 
The RKZ-xx2005D and RxxP22005D can power silicon-carbide (SiC) MOSFET drivers in electric vehicles (EVs), renewable-energy conversion, and high-power industrial drives.
The converters are claimed to have superior isolation, providing up to 4.0 or 5.2kV DC to ensure long-term safety in the presence of high potential differences between control and power circuitry in SiC-MOSFET applications.
By providing asymmetrical +20/-5V outputs, the converters enable the gate driver to apply optimal turn-on and turn-off voltages.
As unregulated 2W converters, the RKZ-xx2005D and RxxP22005D’s power-sharing outputs can be used with equal-power (asymmetrical current) or equal-current (asymmetrical power) loads.
Both operate at up to 85% efficiency, and are available with input voltages of 5.0, 12, 15 or 24V. Operating range is -40 to +100°C (with derating). They also have UL60950 and IEC/EN60950 certification, and comply with RoHS2 and REACH. They are also covered by the manufacturer’s three-year warranty.
