Vicor PI3325 Buck Regulators | DigiKey Daily

Vicor’s PI3325 Cool-Power® ZVS buck regulators are highly integrated system-in-package regulators that output 5 V at up to 20 A for point of load applications. The PI3325 integrates the controller, power switches, and support components in a 10 x 14 mm LGA package and uses a high-performance Zero-Voltage Switching topology to provide best-in-class efficiency, with pulse skipping at light loads. The regulator only requires an output inductor and minimal passives for a complete, cost-effective design that occupies just 740 mm2 of PCB area. It operates from a 14 V to 42 V supply, and supports parallel operation with automatic current sharing for applications with higher current requirements. Vicor’s PI3325 supports fast and slow current limits, integrates a differential amplifier for remote sensing, and has adjustable soft start and tracking.
