PI3740-00
PI3740-00 is ZVS Regulators manufactured by VICOR.
Description
The PI3740-00 is a high-efficiency, wide input and output range DC-DC ZVS Buck-Boost Regulator. This high-density System‑in‑Package (Si P) integrates controller, power switches, and support ponents. The integration of a high-performance Zero‑Voltage Switching (ZVS) topology within the PI3740-00 increases point-of-load performance, providing best-in-class power efficiency.
The PI3740-00 requires an external inductor, resistive divider and minimal capacitors to form a plete DC-DC switching mode buck-boost regulator.

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 fast dynamic response to line and load transients.
