2W DC/DC Converter, Input 10.8…13.2V, Output +20V/-5V / +50mA/-200mA, SIP7

High slew rate SiC transistor drivers require an isolated asymmetric supply of +20/-5V or +15/-3V with high isolation voltage and low isolation capacitance. The RxxPxxyyD series have been specially designed to fulfill this demanding requirement with 6400VDC isolation and <10pF isolation capacitance. The DC/DC converters can be used with equal power (1W + 1W) or equal current (1.6W + 0.4W) driver applications as the dual outputs feature automatic power sharing. The internal transformer uses a pot-core to physically separate the input and output windings, yet the converter still fits into an industry standard SIP7 case. Input voltage options of 5, 12, 15 or 24V are available and the RxxP2xxyyD series is safety certified to the latest UL/IEC62368 standard.
