The Murata Power Solutions has revealed the PAH series that the company describes as high efficiency, medium-power DC/DC converters that can deliver up to 450W output. The compact modules measure 58 x 61 x 12.7mm and comply with the DOSA half-brick footprint. The company added that the devices are aimed at power amplifiers, wireless networks and other telecom applications.

The PAH series has been optimised to meet the demanding dynamic load requirements for power amplifier applications, indicated Murata. Typically, power amplifiers can switch very quickly from very light load to maximum load conditions. In addition, the electrical design of the modules offers tight line and load regulation together with low Vout ripple/noise, touted the firm.

The modules' mechanical design incorporates a baseplate that provides conduction cooling for demanding thermal environments found in outdoor sealed box applications and telecommunications equipment cabinets.

Murata Power Solutions PAH series

Murata Power Solutions PAH series. High efficiency, medium-power DC/DC converters that can deliver up to 450W output.

The PAH series was designed to deliver full output power over the entire telecommunications input voltage range of 36-75VDC. The PAH-28/16-D48 module will provide 28VDC output at up to 16A (450W). The output can be trimmed over a wide range from 16.8-32.2VDC, meeting the requirements of many standard and non-standard applications. Other models available include the PAH-28/12.5-D48, providing 12.5A/350W output, and the PAH-53/8.5-D48, which has a 53VDC/8.5A output rated at 450W, detailed Murata.

Safety features such as thermal shutdown, output over-voltage, input under-voltage and short circuit protection are included across the entire PAH range. All models are certified to UL/EN 60950, CSA-C22.2 with input to output isolation rated at 2250VDC, basic insulation.

In OEM quantities, prices come at $34, with delivery from stock to 16 weeks.
