Fe1766 - Product Overview

The Fe1766 integrated voltage regulator is a single-output, self-contained power converter designed to deliver very high current close to advanced digital loads.

Its 16-phase interleaved buck converter uses a fully integrated powertrain that includes Ferric’s advanced power inductors, power switches, FETs, capacitors, and digital control circuitry.

The Fe1766 combines high current capability, precise voltage regulation, integrated power management, and fast transient response in a compact package designed to reduce board area, layout complexity, and external component count.

Fe1766 has been recognized with an EDN Product of the Year Award in the Power category.
‍
The award highlights a solution that sets new benchmarks for current density, enabling next-generation high-performance SoCs, data center processors, and advanced platforms including xPUs, ASICs, and FPGAs.
