Vicor Corporation has introduced its high density, low profile, integrated VIA PFM™ ac-dc front-end power modules. VIA PFM ac-dc front-end converter modules achieve a power density of 8 W/cm3 (127 W/in3) supplying an isolated, PFC regulated 24 V or 48 V SELV dc output at up to 400W from the universal ac input range of 85 to 264 V with 93% peak efficiency. The VIA PFM is 5X thinner than traditional 1U supplies, offering unique design advantages to power system architects challenged by size constraints. With its 9-mm thin profile and 36-mm width, the VIA PFM can be mounted on the sidewall of any typical 1U chassis, saving valuable real estate.
Recommended: 1206- and 1210-size MLCCs in the over-100µF range
Thermally adept VIA PFMs may be chassis mounted and conduction cooled to eliminate fans, thereby improving overall system reliability and further minimizing the power system footprint. High density, high efficiency and low thermal resistance make VIA PFM front-end modules well-suited for a wide range of end-market applications, including small cell wireless base stations, size constrained LED lighting applications, industrial and automation systems.

Vicor’s online PowerBench™ design tool suite enables designers to model a complete AC to PoL power system with a modular power component design methodology. The PowerBench tool suite provides the ability to quickly configure and visualize end-to-end power systems and dynamically analyze system performance, accelerating design cycles and reducing development costs. Pricing starts at $107 for OEM quantities.
