Product Description:

The PI33xx is a family of high-efficiency, wide-input-range DC-DCZVS Buck regulators integrating controller, power switches andsupport components all within a high-density System-in-Package(SiP). The integration of a high-performance Zero-VoltageSwitching (ZVS) topology, within the PI33xx series, increases pointof-load performance providing best-in-class power efficiency. ThePI33xx requires only an external inductor and minimal capacitors toform a complete DC-DC switching-mode Buck Regulator.

The ZVS architecture also enables high-frequency operationwhile minimizing switching losses and maximizing efficiency. Thehigh-switching-frequency operation reduces the size of the externalfiltering components, improves power density, and enables veryfast dynamic response to line and load transients. The PI33xx seriessustains high switching frequency all the way up to the rated inputvoltage without sacrificing efficiency and, with its 20ns minimumon-time, supports large step-down conversions up to 36VIN.
