Ferric has launched the Fe1767 Newport, a 145 A dual-sided integrated voltage regulator (IVR) designed for AI and high-performance processors. The Fe1767 Newport is built around a direct vertical power path intended to reduce power delivery network (PDN) impedance and limit voltage droop during fast processor load transients.
Newport brings input power in from the PCB-facing side of the package and delivers regulated output toward the processor. Ferric reports that, under equivalent load-step conditions, Newport cuts transient droop by 19% to 30% versus competing IVRs, and by up to approximately 57% versus traditional lateral power delivery. The company also reports a 42% to 63% reduction in power rail PDN impedance compared with backside PCB attachment, depending on integration configuration.
The Fe1767 Newport is rated for 145 A thermal design current and 2.9 A/mm² current density in a 5.6 × 8.9 × 1.2 mm package (49.8 mm² footprint). Ferric lists efficiency of up to 90.5% at 1.8 V input and 0.75 V output. Supported input voltage range is 1.2 V to 2.0 V, with output from 0.25 V to 1.25 V. Nominal switching frequency is 15 MHz, programmable from 10 MHz to 60 MHz.
For processor power delivery, the engineering trade is usually straightforward: tighter transient response typically requires lower PDN impedance and careful control of current loops, but doing that in the immediate vicinity of a high-power package is mechanically and thermally constrained. A dual-sided IVR that pushes current through a shorter vertical path is a direct attempt to buy back droop margin, which can translate into reduced voltage guardbands and less output capacitance—if the integration and layout details cooperate in a real socket and board stack-up.
Noah Sturcken, CEO of Ferric, said, “Delivering current is only part of the challenge—the harder problem is delivering it to the processor without excessive impedance and voltage droop.” He added, “Newport’s dual-sided architecture shortens that path, giving processor designers tighter voltage regulation in a compact, high-current solution.”
The Fe1767 Newport is currently sampling, with samples and evaluation boards available to qualified customers. More information is available at Ferric.
