Eighth-Brick DC-DC Modules Have Ultra-Wide VIN Range

Murata Power Solutions' UWE eighth-brick DC/DC power modules are the industry's first eighth-brick to deliver 12 Vout at 120 W from a nominal 12 , 24, or 28 Vdc source. The UWE-12/10-Q12xx-C series' 4:1 VIN range of 9-  36 V, industry standard DOSA compliant form factor, optional integrated baseplate, and high efficiency makes it ideal for high reliability systems and systems requiring battery backup. The UWE-12/10-Q12xx-C will operate down to 9 Vin, 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. Significant overall system cost reductions can be achieved when employing this eighth-brick solution compared to equivalent quarter- or half-brick solutions.

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

The UWE-12/10-Q12-C isolated DC/DC power converter represents the next generation converters in the industry standard eighth-brick package with up to 120 W of available output power. These DC-DC converters are designed for systems employing 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 12 V @ 120 W is required from a 9-36Vdc source including applications where extreme operating temperatures will be required The modules feature an operating temperature range of -40 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.
