Notes:

Note5: The RP20-FW 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.

Note6: The ON/OFF control function can be positive or negative logic. The pin voltage is referenced to -Vin pin.
