Murata Power Solutions has introduced a new range of isolated single output DC/DC converters that achieve industry leading power density, efficiency and regulation. Devices from the MEV3 series offer 3W of available output power in a previously rated 2W package to give designers potential board space savings of up to 68%.

Supplied in an industry standard SIP package with overall dimensions of 0.774in. (19.65mm) x 0.301in. (7.65mm) x 0.4in. (10.15mm), the MEV3 series is ideally suited to providing local supplies on control system boards. The fully encapsulated UL 94V-0-rated design uses toroidal magnetics and requires no external heatsinking or components helping to simplify implementation in new designs and reduce overall Bill of Materials costs.

The MEV3 series has a typical efficiency level of 83% and offers a choice of input voltages of either 5V or 12V and single output voltages of 5V, 9V, 12V or 15V. All models in the range have a wide operating temperature range of -40°C to +85°C at full 3W load and have the added benefit of 3kVDC galvanic isolation (1 minute). Power density is 1.9W/cm³ offering a significant improvement compared to the previous industry standard 3W power density of 0.9W/cm³.

Industry standard pinout MEV3 DC/DC converters provide a pin compatible power upgrade path from Murata Power Solutions’ 1W NMV/MEV and 2W NMK series’. UL 60950 recognition is pending for all models in the range.
