Vicor’s MIL-COTS 28-V dc-dc V•I chip modules consist of a 28-Vdc input PRM regulator and a family of VTM current multipliers with output voltages from 1 Vdc to 50 Vdc. Each module weighs 0.5 oz and measures 1.28 in. x 0.87 in. x 0.26 in. The PRM and VTM chipset provides the full functionality of a dc-dc converter and flexible thermal management in mission-critical portable and airborne applications.
A PRM and VTM chipset can provide up to 100 A or 115 W for a system density of 172 A/in3 or 198 W/in3, and the modules may be paralleled for higher power arrays. A compatible filter (M-FIAM7) is available that provides EMI filtering in compliance with MIL-STD-461 and transient suppression in compliance with MIL-STD-1275, MIL-STD-704 and DO-160. A MIL-COTS PRM and VTM chipset is available for less than $170 in OEM quantities. Evaluation boards are priced at $219.00 each.
