a more comprehensive range of transient and EMI spec compliance. By providing brick-like modularity and ease-of-use in a smaller form factor, the new VIA DCM and MFM modules enable system designers to develop extremely dense, low profile, high performance products fast. The new solutions help you get to market faster by eliminating many of the uncertainties and compliance problems traditionally associated with military application power design. New MIL-COTS Parts Four new MIL-COTS (M-Grade) versions are available now, providing operation down to -55°C, in the 28V (16 – 50 VDC input voltage range) 3414 VIA DCM family with nominal output voltages of 5V, 12V, 24V and 28V and up to 320 Watts of output power. Complementing these MIL-COTS VIA DCMs is a new MFM 28V filter module (MFM filter) This extremely dense, low profile filter provides front-end transient protection and EMI filtering when used with any Vicor M-Grade 28V 3414 VIA DCM module. This combination enables power engineers to rapidly meet conducted emissions and conducted susceptibility requirements per MIL-STD- 461E/F and input transients per MIL-STD-704A/E/F and MIL-STD-1275D/E. The MFM 28V filter module is housed in a 1714 VIA package (size: 1.76” x 1.40” x 0.36” / 44.6 mm x 35.5 mm x 9.3 mm), accepts an input voltage of 16 – 50 VDC and can deliver up to 350 Watts of power.

select from continuous operation, pulse-skipping and low ripple Burst Mode operation during light loads. Its current mode architecture provides easy loop compensation, fast transient response and excellent line regulation. Output current sensing is accomplished by measuring the voltage drop across the output inductor (DCR) for the highest efficiency or by using an optional sense resistor. Current foldback limits MOSFET heat dissipation during overload conditions. Additional features include up to 98% duty cycle (useful when powered from a battery during discharge), an internal LDO that powers the gate drive from the input voltage or EXTVCC and a power good output signal. The LTC7800 is available in a 20-lead 3mm x 4mm QFN thermally enhanced package which is pin compatible to the LTC3891. Two operating junction temperature grades are available with extended and industrial versions from –40 to 125°C and a high temp automotive grade version from –40°C to 150°C. The 1,000-piece price starts at $3.47 each.

Five new MIL-COTS parts help simplify designs and optimize SWaP-C attributes The VIA DCM family are ruggedized modular DC-DC converters in a thermally adept, low profile (9.3 mm) VIA package, with wide input voltage range specifications and isolated, regulated high efficiency outputs. This new DC- DC converter family, features enhanced functionality and performance, including EMI filtering, transient protection, inrush current limiting, as well as a secondary-referenced control interface for trim, enable and remote-sensing. 3x More Power and Lower Profile Vicor’s new solutions are approximately 2.5X more power dense by volume and approximately 3X more power dense by weight than the closest competitor. Designers can expect better thermal performance and
