The ISL70321SEH evaluation boards highlight an innovative turn-on and turn-off sequencer solution for multi-voltage space-based applications using point-of-load (POL) DC/DC voltage converters. The ISL70321SEHEV1Z platform provides a single IC 4-event evaluation platform, whereas the ISL70321SEHEV2Z provides a dual cascaded IC 8-event evaluation platform. Both evaluation boards are provided on the same PCB design and are both available from inventory in the desired configuration.
