High power V·I chip module in miniature package

27 June 2007 Power Electronics / Power Management

Vicor has announced the availability of MIL-COTS 28 V DC-DC V·I Chip modules. This new product line consists of a 28 V d.c. input PRM regulator and a family of VTM current multipliers with output voltages from 1 to 50 V d.c. The PRM and VTM chipset provides the full functionality of a DC-DC converter with high efficiency and higher power density, fast transient response, low noise, and flexible thermal management. With each module weighing only 15 grams and measuring just 32,5 x 22 x 6,6 mm, the chipset offers specific advantages for designing power systems 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 10,5 A/cm³ or 12,1 W/cm³ and because the PRM can be located, or factorised, remotely from the point of load, these current and power densities can effectively be doubled at the load itself. The modules may be paralleled for higher power arrays and 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.
