Dengrove – New energy-efficient DC-DC converters optimized for SiC power applications

RECOM's latest DC-DC converters are now available from Dengrove Electronic Components. They offer the requisite features needed to power silicon-carbide (SiC) MOSFET drivers in efficiency-focused applications like electric vehicles (EVs), renewable-energy conversion, and high-power industrial drives. The RKZ-xx2005D and RxxP22005D series incorporate superior isolation, providing up to 4kVDC or 5.2kVDC respectively to ensure long-term safety in the presence of high potential differences between control and power circuitry in SiC-MOSFET applications. By providing asymmetrical +20V/-5V outputs, the converters enable the gate driver to apply optimal turn-on and turn-off voltages (VGS). Unlike conventional silicon power transistors, SiC MOSFETs require high VGS for full turn-on, and negative VGS for fast turn-off, to minimise RDS(ON) and switching losses for best overall energy efficiency. As unregulated 2-Watt converters, the RKZ-xx2005D and RxxP22005D feature power-sharing outputs that can be used with equal-power (asymmetrical current) or equal-current (asymmetrical power) loads. The RKZ-xx2005D and RxxP22005D series operate at up to 85% efficiency, and are available with input voltages of 5V, 12V, 15V or 24V. They benefit from a wide operating temperature range from -40C to +100C (with derating), UL60950 and IEC/EN60950 certification, and RoHS2 and REACH compliance, says the company.
