Efficiency up to 84% Features Low deviation (10%-100% load) DC/DC Converter 1kVDC and 2kVDC isolation option IEC/EN/UL60950-1 safety certified Unregulated -40C to +100C operating temperature range Converters 1W SIP4 package RO/E Description 1 Watt The RO/E series is an unregulated DC/DC converter in standard SIP4 package style. This series has SIP4 been designed to offer exceptionally high efficiency at low loads, an extended operating temperature range and low deviation (10% to 100% load). Uses include applications with restricted energy budget and industrial applications where a high efficiency level is required. Single Output Selection Guide Part nom.
