3kv ISOLATED UNREGULATED DUAL OUTPUT DC/DC CONVERTER ExxxxS-1W SERIES DESCRIPTION The ExxxxS-1W series of industrial temperature range DC/DC converters are the standard building blocks for on-board distributed power systems. They are ideally suited for providing dual rail supplies on primarily digital boards with the added benefit of galvan ic isolation to reduce switching noise. All of the rated power may be drawn from a single pin provided the total load does not exceed 1 watt. FEATURES � RoHS compliant � Power sharing on output � Efficiency up to 80% � 3kVDC isolation � Power density up to 0.85W/cm3 � 5V , & 12V input � Wide temperature performance at full 1 Watt load, –40°C to � 5V, 9V, 12V and 15V output 85°C � Internal SMD construction � Dual output from a single input rail � Fully encapsulated with toroidal magnetics � UL 94V-0 package material � No external components required � No heatsink required � MTTF up to 1.697 million hours � Footprint from 1.17cm2 � No electrolytic or tantalum capacitors � Industry standard pinout SELECTION GUIDE Input Output Output Input Current Voltage Voltage Current (Rated Load) (V) (V) (mA) (mA) % pF kHrs E0505S-1W 5 ±5 ±100 289 69 28 1697 E0509S-1W 5 ±9 ±55 267 75 32 682 E0512S-1W 5 ±12 ±42 260 77 34 343 E0515S-1W 5 ±15 ±33 256 78 36 188 E1205S-1W 12 ±5 ±100 120 69 33 559 E1209S-1W 12 ±9 ±55 113 74 46 375 E1212S-1W 12 ±12 ±42 111 75 55 243 E1215S-1W 12 ±15 ±33 110 75 54 154 E2412S-1W 24 ±12 ±42 52 80 65 134 Order Code Efficiency Isolation Capacitance MTTF1 Package Style SIP SIP When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up.
