Overview
The PI3740-00-LGIZ is a high-efficiency, wide input and output range DC-DC Zero-Voltage Switching (ZVS) Buck-Boost Regulator produced by Vicor Corporation. This regulator is part of a high-density System-in-Package (SiP) that integrates a controller, power switches, and support components. The ZVS topology enhances point-of-load performance, providing best-in-class power efficiency and minimizing switching losses. The regulator requires an external inductor, a resistive divider, and minimal capacitors to form a complete DC-DC switching mode buck-boost regulator.
