ISOLATED DC/DC CONVERTERS
48 Vdc Input
28 Vdc /25 A Output
Output Trim Equations
1. Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin and Sense(-) pin. The Trim Up resistor should be connected between the Trim pin and the
Sense(+) pin. Only one of the resistors should be used for any given application.
Note:
Vo_req=Desired(trimmed) output voltage[V], Output voltage Vo=28 V
2. Output Voltage Adjustement by applying external voltage:
Vout=Trim Terminal Voltage X Nominal Output Volgage.
