Murata Power Solutions’ fully isolated HPH series of DC/DC converters affords users a practical solu-
tion 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.
Using both surface-mount technology and pla-
nar 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, xed-
frequency topology along with synchronous output
rectifi cation to achieve a high effi ciency. This
effi ciency, coupled with the open-frame package
that allows unrestricted air fl ow, 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 control (available with posi-
tive or negative logic). Standard features also include
input undervoltage shutdown circuitry, output
overvoltage protection, output short-circuit and
current limiting protection and thermal shutdown.
All devices are certifi ed to IEC/UL/EN60950-1, 2nd
Edition safety standards and carry the CE mark
(meet LVD requirements).
