ISOLATED UNREGULATED DUAL OUTPUT DC/DC CONVERTER BxxxxS-2W SERIES DESCRIPTION The BxxxxS-2W series of DC/DC Converters is particularly suited to isolating and/or converting DC power rails. The galvanic isolation allows the device to be configured to provide an isolated negative rail in systems where only positive rails exist. The wide temperature range guarantees startup from –40°C and full 2 watt output at 85°C. FEATURES � RoHS compliant � 5V & 12V input � Single isolated output � 5V, 9V, 12V & 15V output � 1kVDC isolation � No heatsink required � Efficiency up to 85% � Internal SMD construction � Wide temperature performance at full 2 watt load, –40°C to � Fully encapsulated with toroidal magnetics 85°C � No external components required 3 � Power density 1.44W/cm � MTTF up to 2327 khours � UL 94V-0 package material � Custom solutions available � PCB mounting 2 � Footprint from 1.46cm � Industry standard pinout SELECTION GUIDE Input Output Output Input Current Voltage Voltage Current (Rated Load) (V) (V) (mA) (mA) % pF kHrs B0505S-2W 5 5 400 513 78 19 2327 B0509S-2W 5 9 222 492 81 27 1393 B0512S-2W 5 12 167 479 84 32 832 B0515S-2W 5 15 133 481 83 27 481 B1205S-2W 12 5 400 207 81 28 716 B1209S-2W 12 9 222 198 84 42 593 B1212S-2W 12 12 167 197 85 46 461 B1215S-2W 12 15 133 197 85 54 328 Order Code Efficiency Isolation Capacitance MTTF1 Package Style 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.
