DC/DC converters support energy-efficient designs

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, these converters enable the gate driver to apply optimal turn-on and turn-off voltages (V_GS).

Unlike conventional silicon power transistors, SiC MOSFETs require high VGS for full turn-on, and negative V_GS for fast turn-off, to minimise R_DS(ON) and switching losses for best overall energy efficiency.

As unregulated 2W converters, the devices 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 -40°C to +100°C (with derating), UL60950 and IEC/EN60950 certification, and RoHS2 and REACH compliance.

All units come with RECOM’s 3-year manufacturer’s warranty.
