The Maxi, Mini, Micro Family of DC-DC converters are an integral
part of the company’s overall component power solution
strategy (Figure 1.1), which includes advanced factory and design
automation. The modules are available in an unlimited variety of
standard versions, to the extent that the line between custom and
standard DC-DC converter bricks becomes almost indistinguishable.
The design of the control, magnetic, switching and packaging
elements of the module resulted in a component with a power
density of up to 120W/in3(7,3W/cm3) in three package sizes:
Maxi 4.6 x 2.2 x 0.5in [117 x 55,9 x 12,7mm]
Mini 2.28 x 2.2 x 0.5in [57,9 x 55,9 x 12,7mm]
Micro 2.28 x 1.45 x 0.5in [57,9 x 36,8 x 12,7mm]
The modules have one-third the number of parts of
their predecessors.
While the natural by-products of this reduction in parts count has
improved reliability and lower cost. The extra space also means that
the bulk of the converter can now be devoted almost exclusively to
the power train (i.e., the magnetic and switching elements at the
core of the design).
Resistors can be used to trim the output voltage up or down, if
necessary. Six pin styles, three baseplate options and a variety of
data collection and reporting options are available. The devices
have an operating temperature range of –55 to 100°C and come in
five product grades – E, C, T, H and M.
Other specifications include a typical no-load to full-load regulation
of ±0.5%, a programmable output of 10 – 110%, conversion
efficiencies of up to 92% depending on the voltage combination
and power level chosen, and an input-to-output isolation test
voltage of 3,000VRMS [4,242VDC]. All models are parallelable with
N+M fault tolerance and current sharing. Paralleling architectures
feature DC- or AC-coupled interface.
