Powering AI processors – 48V vertical power delivery changes the game
AI models demand huge current, driving legacy multiphase designs past 50 phases—causing space, thermal, and control limits Vicor addresses
MIL-COTS Maxi, Mini, Micro DC-DC converters
The DC-DC converter that established the "brick" standard
The Maxi, Mini, Micro family of DC-DC converters provides high density, low noise, with advanced power processing. The Maxi, Mini, and Micro converters are compact and efficient, offer wide input ranges, remote sense, enhanced output programmability and low standby dissipation. Low-noise zero-current and zero-voltage switching and advanced power semiconductor packaging provide up to 120W/in3 with low temperature gradients.
Fully encapsulated, Maxi, Mini and Micro series DC-DC converters utilize a proprietary spin-fill process that assures complete, void-free encapsulation making them suitable for the harshest environments. Two grades (H & M), are available with temperatures to –55°C operating and –65°C storage. H & M-Grade modules are qualified to the stringent environmental tests of MIL-STD-810 and MIL-STD-202 and undergo 100% environment stress screening.
