75-W 48-V Input Isolated
DC/DC Converter
Note A:
All data listed in the above graphs has been developed from actual products tested at 25°C. This data is considered typical data for the DC-DC Converter.
Note B:
SOA curves represent operating conditions at which internal components are at or below manufacturer’s maximum rated operating temperature.

Notes:
(1) If (–)Remote Sense is not used, pin 12 must be connected to pin 13 for optimum output voltage accuracy.
(2) The Remote On/Off input has an internal pull-up. If it is left open-circuit the module will operate when input power is applied. A discrete MOSFET or
bipoloar transistor is recommended to control this input. The open-circuit voltage is typically 5V. See application notes for interface considerations.
