PI3311-21
Description
The PI33xx-x1 is a family of high efficiency, wide input range DCDC ZVS-Buck regulators integrating controller, power switches, and support ponents all within a high density System-in Package (Si P). The integration of a high performance Zero Voltage Switching (ZVS) topology, within the PI33xx-x1 series increases point of load performance providing best in class power efficiency. The PI33xx-x1 requires only an external inductor and minimal capacitors to form a plete DC-DC switching mode Buck Regulator.
