Description
The VRYB-40T03x is isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will provide
up to 40 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and low cost.
Features include remote on/off, over current protection and under-voltage lockout. This converter is provided in
an industry SIP package.

Output Trim Equations
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin and GND pin. The Trim Up resistor should be connected between the Trim pin and the Vout
pin. Only one of the resistors should be used for any given application.
