Notes:

Note6: Simulated source impedance of 12μH. 12μH inductor in series with +Vin.

Note7: The RP15 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.

Note8: The ON/OFF control function can be positive or negative logic. The pin voltage is referenced to -Vin pin.
