The Cool-Power® ZVS Buck, PI3325-00-LGIZ, represents the highest current output ZVS buck to date for 24V/28V applications, providing a regulated 5V output at up to 20A. Packaged within a 10 x 14 x 2.5mm LGA SiP package, the PI3325-00-LGIZ addresses the continued need for high power density across a growing spectrum of applications. It also offers pin-for-pin compatibility to a 48V input version ZVS buck, the PI3525-00-LGIZ, enabling designs to be quickly ported from 24VIN capability to 48 VIN.
The PI3325-00-LGIZ requires only an output inductor and minimal passives for a complete, cost-effective, compact design that consumes less than 740mm2 of PCB real estate. Higher current is also achievable by parallel operation of the regulator. The PI3325-00-LGIZ represents one regulator within a new portfolio of higher current 24V ZVS bucks already or soon to be released.
