Typical unit

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.

Fully isolated, 2250Vdc (BASIC)

Input undervoltage shutdown

Output overvoltage protection

Short circuit protection, thermal shutdown

PRODUCT OVERVIEW

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, 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

at elevated ambient temperatures.

Designed to meet UL/EN/IEC 60950-1, CAN/

CSA-C22.2 No. 60950-1 safety approvals

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 over-

voltage protection, output short-circuit and current

limiting protection and thermal shutdown. All

devices meet IEC/UL/EN60950-1 safety standards

and carry the CE mark (meet LVD requirements).
