HPH Series
Isolated, Low VOUT to 70A, Half-Brick DC/DC Converters
Murata Power Solutions’ fully isolated HPH series of DC/DC converters affords users a
practical solution for their low-voltage/high-current applications. With an input voltage range of
36 to 75 Volts, the HPH Series delivers up to 70 Amps of output current from a fully regulated
3.3V output.

PRODUCT OVERVIEW
Using both surface-mount technology
and planar magnetics, these converters
are manufactured on a 2.3" x 2.4", lead-
free, open-frame package with an industry-
standard pinout.
HPH converters utilize a full-bridge,
fixed-frequency topology along with syn-
chronous output rectification to achieve a
high efficiency. This efficiency, coupled with
the open-frame package that allows unre-
stricted air flow, reduces internal component
temperatures thereby allowing operation at
elevated ambient temperatures.
These DC/DC’s provide output trim,
sense pins and primary side on/off con-
trol (available with positive or negative
logic). Standard features also include input
undervoltage shutdown circuitry, output
overvoltage protection, output short-circuit
and current limiting protection and ther-
mal shutdown. All devices meet IEC/UL/
EN60950-1 safety standards and carry the
CE mark (meet LVD requirements).
