Vicor’s First ChiP Modules Deliver 1880 Watts per Cubic Inch from 380Vdc

Vicor Corporation today unveiled the first module utilizing its Converter housed in Package (ChiP) power component platform. Vicor’s new ChiP bus converter modules (BCM®) operate at 1.25 MHz to supply 1.2 kW at 48 V with 98% peak efficiency and 1880 W/in3 power density. Claiming breakthrough performance – 4X the density of competing solutions – this enables efficient, high voltage dc distribution infrastructure in datacenter, telecom, and industrial applications.

Vicor's ChiP platform sets best-in-class standards for a new generation of scalable power modules. Leveraging advanced magnetic structures integrated within high-density interconnect (HDI) substrates with power semiconductors and control ASICs, ChiPs provide superior thermal management supporting unprecedented power density. Thermally-adept ChiPs enable customers to achieve low cost power system solutions with previously unattainable system size, weight and efficiency attributes, quickly and predictably. The advent of ChiPs embodies a modular power system design methodology enabling designers to achieve high performance, cost-effective power systems from ac or dc sources to the Point of Load using proven building blocks.

"ChiPs will enable power system architects to overcome the power density constraints imposed by conventional power solutions," said Patrizio Vinciarelli, CEO, Vicor. "ChiPs maximize performance while minimizing development cost and time to market, yielding superior solutions with the flexibility and scalability of modular building blocks."

With a nominal input voltage of 380V and a K-factor of 1/8, Vicor's new ChiP BCM fixed-ratio power converters supply an isolated 48V distribution bus with a peak efficiency of 98%. With its input range of 260 to 410 V, the new BCM supports outputs ranging from 32.5 V to 51.25 V. BCMs are based on Vicor's ZCS/ZVS Sine Amplitude Converter topology. The 1.25 MHz switching frequency provides fast response time and low noise operation.

Offered in the 6123 ChiP package, the new 380 VDC VI Chip BCMs measure 63mm by 23mm, with a height of only 7.3mm. Initially offered as a through-hole device, package options will also include SMD variants. ChiP BCMs may be paralleled to provide multi-kW arrays and are capable of bi-directional operation to support battery backup and renewable energy applications. Standard BCM features include under-over-voltage lockout, over-current, short circuit and over-temperature protection. ChiP BCMs incorporate digital telemetry and control features that can be configured to meet customer requirements.

"The roll-out of high voltage DC distribution infrastructure is yielding reduced power consumption and operational costs for datacom and industrial facilities," said Stephen Oliver, VP of VI Chip product line, Vicor. "ChiP BCMs provide superior efficiency, density and flexibility the hallmark benefits of the ChiP platform." Vicor's new 6123 VI Chip BCMs are available today. Pricing for OEM quantities is $120.00.
