Features Unregulated Converters * Single output rail * Industry standard pinout * 1kVDC/1s or 2kVDC/1s basic isolation * High efficiency for low power applications * UL94V-0 package material * Optional continuous short circuit protection * Fully encapsulated * Efficiency up to 76% Description The RM series DC/DC converter has been designed for isolating or converting DC power rails with very light loads. Efficiencies are typically 10% higher than a comparable 0.5W or 1W converters run at the same low load. DC/DC Converter RM 0.25 Watt SIP4 Single Output Selection Guide Part Number nom.
