Vicor’s 28 V MIL-COTS VIPAC™is an integrated power system
leveraging the latest advances in DC-DC converter technology
and modular front ends. VIPAC combines application specific
power processing units (PPU) and a choice of chassis styles to
provide fast, flexible and highly reliable power solutions for a
wide range of demanding applications.
The PPU is the core element of the system and incorporates either
Vicor’s M-FIAM5B or M-FIAM9 to provide transient protec-
ion, EMI filtering and inrush current limiting.
t
The web-based VCAD tool enables designers to configure the
PPU with up to three independently regulated outputs having
power levels from 50 to 400 W. Vicor’s Maxi, Mini, Micro Series
DC-DC converters, in industry standard quarter, half and full
brick packages, are used to deliver output voltages from 3.3 to
48 Vdc. Additionally, the wide trim range of the modules can pro-
vide operating voltages as low as 500 mV.
The PPU is comprised of:

PPU
• DC input modular front end
• Vicor’s Maxi, Mini, Micro Series high density
DC-DC converters
• Interface board
• Coldplate or finned chassis
• Choice of output termination styles
The VIPAC is offered in several chassis configurations facilitating
its use in a variety of applications using either conduction,
convection or forced convection cooling. The low profile,
conduction cooled version may be mounted to an existing
cabinet wall, coldplate or heat sink. The 0.5" or 1" finned
versions, available in longitudinal or transverse configurations,
are ideal for use in free or forced convection environments.
The use of standard chassis footprints allowsdifferent input voltage
configurations of theVIPAC to be used interchangeably
depending on system and market requirements.

Output Sequencing
Power up will always occur in the defined sequence stored within the device. Any preprogrammed
power down sequence, except the default, will not be in effect upon loss or removal of the VIPAC
source voltage. Sequenced power down can only be achieved by issuing the requisite commands
through the interface before removing the source voltage.
