description
The Interpoint MFL Series 28-volt DC/DC converters are
rated up to 65 watts with an overall power density of up to 43
watts per cubic inch. On dual output models up to 70% of the
rated output power can be drawn from either the positive or
negative output. These hermetically sealed converters are offered
with standard screening, “ES” screening, or fully compliant to
“883” MIL-PRF-38534 Class H screening. Standard microcircuit
drawings (SMD) are available.
Design Features
The MFL Series converters are switching regulators that use a
quasi-square wave, single ended forward converter design with a
constant switching frequency of 600 kHz.
Isolation between input and output circuits is provided with a
transformer in the forward path and a wide bandwidth magnetic
coupling in the feedback control loop. The MFL uses a unique
dual loop feedback technique that controls output current with
an inner feedback loop and an output voltage with a cascaded
voltage mode feedback loop.
The additional secondary current mode feedback loop improves
transient response in a manner similar to primary current mode
control and allows for ease of paralleling, but without the cost
and complexity.
The constant frequency, pulse-width modulated converters
use a quasi-square wave single-ended forward design. Tight
load regulation is achieved through a wide-bandwidth magnetic
feedback circuit. The output on single MFL models can be
trimmed (see Figure 1 for voltage changes with different resistor
values).
inhibit
The MFL Series converters have two inhibit terminals (INH1 and
INH2) that can be used to disable power conversion, resulting in
a very low quiescent input current and no generation of switching
noise. See the following page for inhibit specifications.
sync
Converters may be synced to an external clock (525 to 675 kHz)
or to one another by using the sync in or out pins. The nominal
free-run switching frequency is 600 kHz.
current share anD Parallel OPeratiOn
Multiple MFL converters may be used in parallel to drive a
common load (see Figure 2). Only single output models with
SENSE and SNS RTN can be used in the share mode. In this
mode of operation the load current is shared by two or three
MFL converters. In current sharing mode, one MFL converter is
designated as a master. The SLAVE pin (pin 11) of the master is
left unconnected and the MSTR/INH2 pin (pin 12) of the master
is connected to the SLAVE pin (pin 11) of the slave units. The
units designated as slaves have the MSTR/INH2 pin (pin 12)
connected to the SNS RTN pin (pin 9). Figure 2 shows the typical
setup for two or three units in parallel. Note that synchronizing
the units together (though shown in the figure) is not required for
current sharing operation. A second slave unit may be placed in
parallel with a master and slave; this requires the TRI pin (pin 3)
of the master unit to be connected to the SNS RTN pin (pin 9).
When paralleled, up to 95% of the total combined power ratings
of the MFL converters is available at the load. Overload and
short circuit performance are not adversely affected during
parallel operation.
