Product Overview
VICBrick high-density converters (up to
120 A/in
3
) are enabled by Vicor's VI Chip
technology. Each VICBrick consists of two
VI Chips: a 36 75 Vdc input Pre-Regulator
Module (PRM) that is paired with an
appropriate Voltage Transformation Module
(VTM) chosen to provide the desired output
voltage. While the ultra-low profile package
conforms to industry-standard quarter-brick
footprint (1.45" x 2.28"), it stands only
0.27" high and achieves 80 A of output current.
Standard outputs include 1.0, 1.2, 1.5 V and
1.8 V at 80 A, 2.5 V at 60 A, 3.0 and 3.3 V
at 45 A, and 5 V at 30 A. Output voltages
can be easily trimmed up or down over a
wide range. Dual output pins are used for
output currents over 50 A.
Utilizing breakthrough Sine Amplitude
Converter (SAC) technology, VICBricks
offer the highest efficiency, lowest noise,
fastest transient response and highest power
density. And because of the VI Chips
highly integrated functionality, VICBricks
have only a fraction of the parts of a typical
DC-DC converter.

INPUT FUSING
VICBricks are not internally fused in order to provide flexibility in power system configuration. Input line fusing of VICBricks
must always be incorporated within the power system. The input line fuse should be placed in series with +IN. Vicor recommends
using the Littlefuse Nano 451/453 series for fusing VICBricks. Please refer to the chart above for appropriate fuse values.
