Team,

We’re using this in a design application where we will be enable 1 channel at a time and not all 4 channels together.

Can a single channel support 35W output ? (Not all 4 channels are ON) ; ie can we do 12V@ 3A ?

Hi Michael,

It's very hard for this device to support 3A due to thermal issue unless there are extra cooling. For 3A, would you consider a lower Rdson device or parallel the channels together?
