28 VOLT INPUT – 30 WATT
DESCRIPTION
The MTR Series of DC/DC converters offers up to 30 watts of
output power from single, dual, or triple output configurations. They
operate over the full military temperature range with up to 84% effi-
ciency. MTR converters are packaged in hermetically sealed metal
cases, making them ideal for use in military, aerospace and other
high reliability applications.
CONVERTER DESIGN
The MTR converters are constant frequency, pulse-width modulated
switching regulators which use a quasi-square wave, single ended,
forward converter design. Tight load regulation is maintained via
wide bandwidth magnetic feedback and, on single output models,
through use of remote sense. On dual output models, the positive
output is independently regulated and the negative output is cross
regulated through the use of tightly coupled magnetics and shunt
regulators. The MTR Series triple output DC/DC converter’s design
includes individual regulators on the auxiliary outputs which provide
for no cross regulation error when a minimum 500 mA load is main-
tained on the main (+5) output.
Indefinite short circuit protection and overload protection are
provided by a constant current-limit feature. This protective system
senses current in the converter’s secondary stage and limits it to
approximately 115% of the maximum rated output current.
MTR converters are provided with internal filtering capacitors that
help reduce the need for external components in normal operation.
For systems that require compliance with MIL-STD-461C’s CE03
standard, Interpoint offers filter/transient suppression modules
(including the FMC-461, FMD-461 and FM-704A series filters) which
will result in compliance. Contact your Interpoint representative for
further details.
SYNCHRONIZATION
Synchronizing the converter with the system clock allows the
designer to confine switching noise to clock transitions, minimizing
interference and reducing the need for filtering. In sync mode, the
converter will run at any frequency between 500 kHz and 675 kHz.
The sync control operates with a quasi-TTL signal at any duty cycle
between 40% and 60%. The sync pin must be connected to input
common pin when not in use.
