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.
The converters are available with standard screening or “ES”
screening
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.
Up to five single output MHP270 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 an 85% current
sharing accuracy over 35% load to full load conditions.
MHP270 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. MHP270 converters have a nominal switching
frequency of 525 kHz, but may be synchronized at any frequency
from 475 to 575 kHz.
MHP270 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 MIL-STD-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 our MIL-PRF-38534 certified facilities.

Undervoltage lock-out – shuts down when the input line voltage
falls below approximately 120 VDC to provide smooth initializa-
tion.
Continuous short circuit protection – current limit set at approxi-
mately 125%.
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.
