Description
The RP08-A series DC/DC converters are certified to UL 60950-1 and cUL 60950-1. This makes them
ideal for all telecom and industrial applications where approved safety standards are required. The
DIP24 package is available in both pinned and SMD case styles and meets military standards for thermal
shock and vibration tolerance.

Notes:
Note4: The RP08 series requires a minimum of 10% loading on the output to maintain specified regulation. Operation under no-load condition will not
damage these devices, however they may not meet all listed specification.
Note5: The ON/OFF control pin voltage is referenced to -Vin pin.
