120W at 12V from an eighth-brick, wide-input-range module

March 02, 2015 // By Graham Prophet
Murata Power Solutions’ UWE eighth brick DC/DC power modules are positioned as the first “1/8 brick” units to deliver 12V output at 120W from a nominal 12V, 24V or 28VDC source.

The UWE-12/10-Q12xx-C series’ 4:1 Vin range of 9-36V, industry standard DOSA compliant form-factor, optional integrated baseplate and high efficiency makes it suitable for high reliability systems and systems requiring battery back up. Operation is maintained down to 9Vin allowing longer battery discharge times in the event of a source failure. The 91+% efficiency rating of these modules also means that they will operate in harsh environments and require less cooling hardware compared to equivalent (larger) power modules. Murata says that significant overall system cost reductions are possible compared to equivalent quarter or half brick solutions.

Applications include industrial, transportation and telecommunications equipment. The units provide 2250Vdc input to output isolation, and options that include an optional baseplate for conduction cooling applications, positive or negative logic control and features, output over voltage protection, thermal shutdown, current limit / short circuit protection and Vout adjust (±10%). These DC/DC converters are designed for systems employing distributed power architectures or intermediate bus architectures and have an operating temperature range of -40 to 85°C.
