ZVS Buck-Boost Family of Switching Regulators
Vicor's ZVS buck-boost family of switching regulators enables fast dynamic response to line and load transients
The Vicor PI37xx is a series of high-efficiency, wide input range DC/DC zero-voltage switching (ZVS) buck-boost regulators integrating controller, power switches, and support components, all within a high-density system in package (SiP). The PI37xx requires only an external inductor and a minimal number of capacitors to form a complete DC/DC switching mode buck-boost regulator. The high switching frequency reduces the size of the external filtering components, improves power density, and enables very fast dynamic response to line and load transients. The PI37xx regulator sustains high switching frequency up to the rated input voltage without sacrificing efficiency and supports large DC/DC conversion ratios. The device can also be configured to operate in constant current mode.
