Switching regulators increase point‑of‑load performance giving excellent power efficiency

Vicor PI358x-00 ZVS Switching Regulators are high input voltage, wide‑input‑range DC-DC ZVS Buck regulators which incorporate a controller and power switches in a high-density 37-pin GQFN (UTAC's Grid‑array QFN) package. The integration of a high-performance ZVS topology, within the series, increases point‑of‑load performance producing best-in-class power efficiency.

Features incorporate a comprehensive input voltage range of 30V to 60V, a power-up into pre-biased mode <6V, and a -20C to +120C operating temperature range. The regulators are parallel capable with single-wire current sharing while allowing fast and slow current limits. Protections incorporate input OCLO/ULVO, OVP, and OTP.

The regulators are ideal for HV to PoL buck regulation applications, computing equipment, communications equipment, industrial equipment, and automotive equipment.
