Murata Power Solutions’ fully isolated Power

Ampliﬁ ers Quarter-Brick series of DC-DC convert-

ers is used in power radio-applications and is

optimized for the new generation of micro cell

transmitter applications requiring up to 150W. With

an input voltage range of 36 to 75 Volts, the PAQ

Series delivers up to 5 Amps of output current from

a fully regulated 29.8V output.

The PAQ offers a wide output voltage range

with the ﬂ exibility to adjust its output voltage with

the range of 23.84 to 32.78V (29.8V nom) that

accommodates multiple power-ampliﬁ ers designs,

industry leading efﬁ ciency (92.5% @29.8Vout full

load), and optimized design to reduce component

count for increased reliability. Design features

include an optional baseplate that is optimized for

RFPA applications being deployed in sealed box

applications with its heat sink ﬁ xed directly to the

host equipment chassis.

The PAQ is designed as an open-frame ¼ brick,

through-hole mounting, with options for positive

or negative logic and optional baseplate. Intended

markets include Micro Base Stations (Micro Cell

Transmitters, RFPA (radio frequency power ampliﬁ ers),

Microwave Radio communications, and Telecom and

Data Equipment applications where a 2:1 input volt-

age, 23 to 33Vout and isolated power is needed.

The PAQ offers Output over voltage, over current

protection, thermal shutdown, Input under-voltage

lockout, and short circuit protection. The option for

adding a baseplate for cold plate applications is

also available with an optional baseplate to ground

connect pin. The modules are designed to meet

Conducted EMI requirement for class B with an

optional external ﬁ lter. The PAQ provides voltage

isolation (basic) from input to output of 2250V. The

PAQ series is certiﬁ ed to safety standards UL/EN/

IEC/CSA 60950-1, 2nd edition.

PAQ Series Up to 150W 29.8V Nom Output Quarter-Brick Isolated DC-DC Converter with 2:1 Wide Input Range 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 +Vin input supply line.
PAGE 13
PAQ Series Up to 150W 29.8V Nom Output Quarter-Brick Isolated DC-DC Converter with 2:1 Wide Input Range Floating Outputs Since these are isolated DC/DC converters, their outputs are “ﬂoating” with respect to their input. The essential feature of such isolation is ideal ZERO CURRENT FLOW between input and output. Real-world converters however do exhibit tiny leakage currents between input and output (see Speciﬁcations).

PAQ Series Up to 150W 29.8V Nom Output Quarter-Brick Isolated DC-DC Converter with 2:1 Wide Input Range Trim adjustments greater than the speciﬁed +10%/–20% can have an adverse affect on the converter’s performance and are not recommended. Excessive voltage differences between VOUT and Sense, in conjunction with trim adjustment of the output voltage, can cause the overvoltage protection circuitry to activate (see Performance Speciﬁcations for overvoltage limits).

There should not be any appreciable ringing or oscillation. You may also adjust the output trim slightly to compensate for voltage loss in any external ﬁlter elements. Do not exceed maximum power ratings.
