Description

The Bel x7PF-20A1A0 is a new high density open frame non-isolated converter series for space sensitive

applications. Each model has a wide input range (10.2V-13.8V) and offers a wide range of output voltage (0.9V

- 5.0V) with a 20A load. An external resistor adjusts the output voltage from its pre-set value of 0.9V to any

value up to the 5.0V maximum. Typical efficiency is 92% at Vo=5V, Vin=12V at full load. Typical features

include remote on/off, under-voltage lockout, over-current protection and short circuit protection.

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

Output Trim Equations

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

Trim Up resistor should be connected between the Trim pin and Ground. Trim values should not be less than

280Ω.
