HPQ-12/25-D48 Series

Isolated 300-Watt Quarter Brick DC/DC Converters

www.murata-ps.com

PRODUCT OVERVIEW

The HPQ-12/25-D48 series offers high output

current (up to 25 Amps) in an industry standard

“quarter brick” package requiring no heat sink for

most applications. The HPQ-12/25-D48 series de-

livers ﬁxed 12 Vdc output at 300 Watts for printed

circuit board mounting. Wide range inputs on the

2.3” x 1.45” x 0.49” converter are 36 to 75 Volts

DC (48 Volts nominal), ideal for datacom and telecom

systems. The ﬁxed output voltage is regulated to

within 0.25ꢀ.

Advanced automated surface mount assembly

and planar magnetics deliver galvanic isolation

rated at 2250 Vdc for basic insulation. To power

digital systems, the outputs offer fast settling to

current steps and tolerance of higher capacitive

loads. Excellent ripple and noise speciﬁcations as-

sure compatibility to CPU’s, ASIC’s, programmable

logic and FPGA’s. No minimum load is required. For

systems needing controlled startup/shutdown, an

external remote On/Off control may use either posi-

tive or negative polarity. Remote Sense inputs com-

pensate for resistive line drops at high currents.

A wealth of self-protection features avoid prob-

lems with both the converter and external circuits.

These include input undervoltage lockout and

overtemperature shutdown using an on-board tem-

perature sensor. Overcurrent protection using the

“hiccup” autorestart technique provides indeﬁnite

short-circuit protection. Additional safety features

include output overvoltage protection and reverse

conduction elimination. The synchronous rectiﬁer to-

pology offers high efﬁciency for minimal heat buildup

and “no heat sink” operation. The HPQ-12/25-D48

series is certiﬁed to full safety standards UL/EN/IEC/

CSA 60950-1, 2nd edition and RFI/EMI conducted/

radiated emission compliance to EN55022, CISPR22

with external ﬁlter.
