Description
The Bel V7PB-15Cxxx is part of the low cost non-isolated dc/dc converter series. The modules use a SIP
package for ease of layout and space savings. The output is closely regulated and the efficiency is typically
93% at 2.5 V output at full load. Typical features include remote on/off, under-voltage lockout, over-current
protection and short circuit protection.

Output Trim Equations
Equations for calculating the trim resistor (in k) given the desired adjusted voltage (Vadj) and the nominal
output voltage of the converter (Vnom) are shown below. The Trim Down resistor should be connected between
the Trim pin and Vout. The Trim Up resistor should be connected between the Trim pin and Ground. Only one of
the resistors should be used for any given application.
