📥 Download Datasheet

General Description

The PTQB425080 power module is single-output isolated DC/DC converter, housed in an industry standard quarter-brick package.

The module is nominally rated up to 200 W with a maximum load current of 25 A.

It delivers an output voltage of 1/6th the input voltage for an input voltage range of 36 V to 55 V, while limiting the output voltage to 10.5 V for an input voltage greater than 55 V.
