Notes:

Note5: An external filter capacitor is required for normal operation. The capacitor should be

capable of handing 1A ripple current for 48V/24V models.

RECOM suggest: Nippon chemi-con KY series, 220μF/100V, ESR 90m

Ω.

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

Note7: Operating frequency for dual output: master (5Vout) 300KHz slave (3.3Vout) 500KHz.

Note8: The ON/OFF control pin voltage is referenced to -Vin pin.
