The RKZ-xx2005D series features DC/DC converters which are especially designed for SiC mosfet
drivers. The modules are available with input voltages of 5, 12, 15, or 24VDC with two
asymmetric outputs of +20VDC and -5VDC. A special feature of this converter is output power
sharing: the RKZ-xx2005D can be used with equal power (asymmetrical current) or equal current
(asymmetrical power) loads. The modules offer 3kVDC or 4kVDC isolation. The operating
temperature range of -40C to +100°C (with derating) meets harsh environmental requirements.
