57,9 x 36,8 x 12,7 mm
Product Overview
This DC-DC converter module uses
2nd Generation power processing, control
and packaging technologies to provide the
performance, flexibility and cost effectiveness
expected of a mature power component.
For example, a plated-cavity core transformer
couples widely separated primary and
secondary windings, resulting in low in-to-
out parasitic capacitance and noise.
High frequency ZCS/ZVS switching,
advanced power semiconductor packaging
and thermal management provide high
power density with low temperature
gradients. Extensive use of silicon
integration results in 1/3 the part count
of a 1st Generation converter.

CONTROL FUNCTIONS - PR PIN
Parallel Operation
The PR pin supports paralleling for increased power with N+1
(N+M) redundancy and phased array capability. Modules of
the same input voltage, output voltage, and power level will
current share if all PR pins are suitably interfaced.
Compatible interface architectures include the following:
DC coupled single-wire interface. All PR pins are directly
connected to one another. This interface supports current
sharing but is not fault tolerant. Minus In pins must be tied to
the same electric potential. See Figure 9.
AC coupled single-wire interface. All PR pins are connected
to a single communication bus through 0.001µF (500V)
capacitors. This interface supports current sharing and is fault
tolerant except for the communication bus. See Figure 10.

• The +Out and –Out
power buses should be
designed to minimize
and balance parasitic
impedance from each
module output to the
load.
• At the discretion of the
power system designer,
a subset of all modules
within an array may be
configured as slaves by
shorting SC to –Out.
• Do not use output
OR’ing diodes with
MicroMods.

• This module is designed for point of load regulation, where remote sensing
is not required. Active voltage drop compensator, as shown here, may be
used in applications with significant distribution losses. Details of this circuit
are available in the design guide.
