Hello, we are trying to order our master boards and the MAX17502EATB+T chip is unavailable until the fall. Does anyone have suggestions for an alternative?
Hello, unfortunately this is a specialized chip and you won’t find a pin compatible device other than a maxim one.
Adapting for another DC/DC converter will necessitate a redesign of the board.
A hack could be to not populate the chip and directly power the board in 3.3v via one of the connectors witch exposes the 3.3v line.
If you only have access to the 24VDC bus, you can use a converter such as TSR1-2433 from tracopower.
