FEATURES

PRODUCT OVERVIEW



For applications requiring improved electrical and

thermal performance, consider Murata’s new PAH

series “half brick” DC-DC power converters. These

compact modules measure 2.3" X 2.4" X 0.5" (58

X 61 X 12.7mm) and offer the industry-standard

Half Brick footprint.

The module provides a 28Vdc (@16A) output and

accepts a wide input voltage range of 36-75Vdc. The

PAH topology offers high efﬁciency (up to 93.5%),

tight line and load regulation, low ripple/noise, and

a fast dynamic load response. A single-board, highly

optimized thermal design contributes to the superior

thermal performance.

Wide Vout trim range (see speciﬁcations)



Industry standard “half brick” package



High efﬁciency: up to 93.5%



Outstanding thermal performance



Standard baseplate for conduction cooled

applications

The PAH Series is ideal for power ampliﬁer

applications, wireless networks, and telecom

applications. The baseplate provides a means for

conduction cooling in demanding thermal environ-

ment conditions.



No output reverse conduction

These half-bricks provide output trim, sense

pins, and primary side on/off control. Standard fea-

tures also include input under-voltage shutdown,

output over-voltage protection, output short-circuit/

current limiting protection, and thermal shutdown.
