The MHP270 Series™ DC/DC converters provide up to 65
watts of output power over -55°C to +100°C temperature range.
MHP270 models operate from a MIL-STD-704 nominal 270-volt
DC power bus with 160 to 400 VDC continuous ­operation with
surges to 450 volts. Isolated outputs include 5, 12, 15, and 28
VDC singles and ±5, ±12 and ±15 VDC duals. Parallel operation
for all loading ­conditions is supported without any requirement for
external components. The converters are available with standard
screening or “ES” screening
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 milliseconds. The units are built as fully hermetic thick film
hybrids in our MIL-PRF-38534 ­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.
Continuous short circuit protection – current limit set at approximately 125%.
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.
Remote sense – Sense lines increase the output voltage to
compensate for IR drops in traces and wires. The voltage
compensation can be up to a maximum of 10% of nominal output
voltage to maintain tightly regulated voltage at the load.
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.
Output Voltage Options
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

Features
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.
The MHP270 Series converters are capable of providing other
output voltage options in addition to those characterized on this
datasheet. Contact your sales representative to discuss other
output voltage options, www.interpoint.com/contacts.

• Dotted lines are optional connections
• Sync in should be connected to input common if not used
• Synchronizing the converters eliminates beat frequencies during current sharing (parallel operation)
• From 2 to 5 converters can be paralleled for up to 276 watts of output power.
• These converters are not designed for use in redundant systems
• If deviating from this diagram, please consult our applications engineers:
