Vicor has extended its family of Cool-Power® 48V ZVS buck regulator modules by introducing the PI3523, PI3525 and PI3526, which provide output currents twice as high as existing parts in the family in a package just 40% larger.

This means that the Cool-Power 48V family now provides scalable power options for direct-to-point-of-load applications operating from a 48V nominal input and drawing a current of up to 22A.

The PI352x modules only require an output inductor and few passive components to make a complete and cost-effective design which occupies less than 740mm2 of PCB area. Supporting easy paralleling in combinations of up to three regulators, the PI352x devices can be scaled to support higher-current loads.
