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.
Features
Undervoltage lock-out – shuts down when the input line voltage
falls below approximately 120 VDC to provide smooth initialization.
Continuous short circuit protection – current limit set at approximately 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.

Notes
1. Share operation not characterized for dual outputs.
2. Up to 80% of the total output power is available from either output
provided that the opposite output is simultaneously carrying 20% of the
total output power. One of the outputs must always provide a minimum
of 20% of the total output power to meet cross regulation. Negative Vout
cross regulation is referenced to 50%/50% balanced loads (at 100% of
total rated output power - full load).
3. Assumes balanced loads on the outputs.
