Features and Applications

The PI3311-01-LGIZ is a Part of PI33XX family 1 Vout 18 A high efficiency, wide input range DC-DC ZVS-Buck regulators integrating controller, power switches, and support components all within a high density System-in-Package (SiP).

The integration of a high performance Zero-Voltage Switching (ZVS) topology, within the PI33XX series, increases point of load performance providing best in class power efficiency. The PI33XX requires only an external inductor and minimal capacitors to form a complete DC-DC switching mode buck regulator.
