Description

The Bel xRPF-15B1AC 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 can be trimmed from 1.2 Vdc

to 3.3 Vdc. The efficiency is typically 93% at 3.3 Vdc output at full load. Typical features include remote on/off,

under-voltage lockout, over-current protection and short circuit protection.

1. Power good delay time is the time from output voltage in full regulation to power good asserted.

2. The power good signal is an open collector output. When the output of the module is higher than 90%

of the nominal set point, the power good pin is high.

Output Trim Equation

Equation for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) is shown below. The

Rtrim resistor should be connected between the Trim pin and Ground.
