High isolation 2W converter Features 3kVDC/1s and 4kVDC/1s basic isolation DC/DC Converter UL94V-0 package material Optional continuous short circuit protected Unregulated Efficiency up to 84% Converters Suitable for IGBT applications RKZ Description 2 Watt The RKZ Series of 2W DC/DC Converters are certified to EN60950-1. This makes them suitable for high SIP7 end industrial applications such as IGBT driver circuitry. The RKZ converters are pin-compatible with the RK and RH converter series, offering a simple way to upgrade a 1W high isolation supply to 2W. Single and Dual Output Selection Guide Part nom.
