PI354x Cool-Power ZVS Buck Regulators utilize the integration of a high performance ZVS topology that enables 48 V direct to PoL without sacrificing performance. With step-down regulation from a higher voltage source, engineers can deploy more efficient power distribution architectures, reduce I2R losses, and eliminate costly and inefficient intermediate conversion stages. Features include: PI354x series operates from 36 Vin to 60 Vin; Regulates an output voltage ranging from 2.2 V to 14 V, with output current delivery up to 10 A; and Power delivery can be further increased by using single wire current sharing without any additional components.
