PI3312-21 Datasheet | VICOR

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. Device Output Voltage Set Range PI3311-x1-LGIZ 1.0V 1.0 to 1.4V PI3318-x1-LGIZ 1.8V 1.4 to 2.0V PI3312-x1-LGIZ 2.5V 2.0 to 3.1V PI3301-x1-LGIZ 3.3V 2.3 to 4.1V Table 1 - PI33xx-x1 portfolio IOUT Max 15A 15A 15A 15A The ZVS architecture also enables high frequency operation while minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external filtering ponents, improves power density, and enables very fast dynamic response to line and load transients. The PI33xx-x1 series sustains high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20ns minimum on-time, supports large step down conversions up to 36VIN.
