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.

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, fixed-
frequency topology along with synchronous output
rectification to achieve a high efficiency. This
efficiency, coupled with the open-frame package
that allows unrestricted air flow, reduces internal
component temperatures thereby allowing operation

input undervoltage shutdown circuitry, output
overvoltage protection, output short-circuit and
current limiting protection and thermal shutdown.
All devices are certified to IEC/UL/EN60950-1, 2nd
