Keywords:Murata Power Solutions  DC-DC converter  power module 

Murata Power Solutions has introduced its UWE eighth-brick DC/DC power modules that claim to offer 12Vout at 120W from a nominal 12V, 24V or 28VDC source. According to the company, the UWE-12/10-Q12xx-C series' 4:1 VIN range of 9V to 36V, industry standard DOSA compliant form factor, optional integrated baseplate, and high efficiency makes it suitable for high reliability systems and systems requiring battery backup.

The UWE-12/10-Q12xx-C will operate down to 9VIN, allowing longer battery discharge times in the event of a source failure. The 91+ per cent 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. Significant overall system cost reductions can be achieved when employing this eighth-brick solution compared to equivalent quarter- or half-brick solutions.

UWE-12/10-Q12xx-C series

The UWE-12/10-Q12xx-C is geared for high reliability industrial, transportation and telecommunications equipment requiring 12VDC from a source of 12V, 24V or 28VDC. Murata developed the UWE-12/10-Q12xx-C to address the need for a 12VOUT DC-DC converter able to deliver 120W and provide 2250VDC input to output isolation from a 9V to 36V source. Aimed to offer the power systems architect options that include an optional baseplate for conduction cooling applications, positive or negative logic control and features, 2250VDC I/O isolation, output overvoltage protection, thermal shutdown, current limit/short circuit protection, and VOUT adjust (±10 per cent).

The DC-DC converters are intended for systems using distributed power architectures or intermediate bus architectures in applications that include but are not limited to battery charging/back-up systems, telecommunications, lighting applications, motor control and anywhere that 12V at 120W is required from a 9V to 36VDC source including applications where extreme operating temperatures will be required. The modules feature an operating temperature range of -40°C to 85°C.

Samples are available from stock. Lead-time is 16 to 20 weeks. Pricing in OEM quantities is in the mid-$30 range.
