DESCRIPTION
The MHP270 Series™ DC/DC converters provide up to 65 watts of
output power over the full –55°C to 100°C temperature range.
MHP270 models operate from a MIL-STD-704 nominal 270 volt DC
power bus – from 160 to 400 VDC continuous operation with surges
to 450 volts – and provide isolated outputs at 5, 12, 15, and 28 VDC.
Parallel operation for all loading conditions is supported without any
requirement for external components.
MHP converters meet a wide variety of military/aerospace performance and environmental specifications. Their continuous operation
input voltage (160 to 400) meets the normal operating limits of MILSTD-704. The unit shuts down above approximately 425 volts, but
it is rated to withstand a surge of up to 450 volts for 50 msec. The
units are built as fully hermetic thick film hybrids in Interpoint’s MILSTD-1772 certified facilities.
MHP270 DC/DC converters are constant frequency, pulse width
modulated switching power supplies which use a quasi-square
wave, two-switch single-ended forward converter design. Tight load
regulation is achieved through a wide-bandwidth magnetic feedback
circuit.
The MHP270 Series offer a complete list of standard features which
include:
Up to five single output MHP converters may be used in parallel to
power a single load by simply connecting the share pins of all units.
Units in this configuration have a 85% current sharing accuracy over
all loading conditions.
Continuous short circuit protection – current limit set at approximately 125%.
MHP Series of converters feature a flexible synchronization scheme
in which units may be synchronized to an external clock or to one
another by using sync in and sync out pins provided on each unit.
MHP converters have a nominal switching frequency of 600 kHz, but
may be synchronized at any frequency from 525 to 675 kHz.
Undervoltage lock-out – shuts down when the input line voltage falls
below approximately 120 VDC to provide smooth initialization.
Soft-start – controlled start-up at turn-on, release from inhibit, and
recovery from load fault conditions.
Remote sense – to provide automatic compensation for voltage
drops on output lines on single output models.
