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 PAH Series is ideal for power amplifier

applications, semiconductor test equipment,

wireless networks, and telecom applications.

The baseplate provides a means for conduc-

tion cooling in demanding thermal environment

conditions.

The module provides a 53Vdc or 48Vdc output

at 8.5 Amps and accepts a wide input voltage

range of 36-75Vdc. The PAH topology offers high

efﬁ ciency (up to 94%), 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.

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.

PAH 48, 53 Vout, 450W Series Isolated, up to 450 Watt, Half-Brick DC-DC Converters TECHNICAL NOTES Input Fusing Certain applications and/or safety agencies may require fuses at the inputs of power conversion components. Fuses should also be used when there is the possibility of sustained input voltage reversal which is not current-limited. For greatest safety, we recommend a fast blow fuse installed in the ungrounded input supply line.

This on/off cycling is called “hiccup mode”. The hiccup cycling reduces the average output current, thereby preventing excessive internal temperatures. A short circuit can be tolerated indeﬁnitely. Remote Sense Input Sense inputs compensate for output voltage inaccuracy delivered at the load.
