Description
The Bel V7PB-15Exxx series are part of the low cost non-isolated DC/DC power converter series. These modules use a SIP package for ease of layout and space savings. The output is closely regulated and the efficiency at 3.3V output is typically 92% at full load. Typical features include remote on/off, under-voltage lockout, wide input voltage range, wide output trim range, 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.
