The MAXREFDES1218 is an active-clamp forward power supply that delivers up to 4A at 24V from a 18V to 36V supply voltage. It is designed for industrial equipment that needs high power isolated power supply. The typical application of the MAXREFDES1218 is an IO-Link® application that needs a 24V isolated voltage from an industrial 24V supply voltage.

The MAXREFDES1218 illustrates techniques using the active-clamp forward controller to generate isolated voltages. This document explains how the MAX17599 activeclamp forward controller can be used to generate 24V isolated voltage from 18V to 36V input voltage. An overview of the design specification is shown above.
