Murata Single Output Isolated DC-DC Converters Offer 3W Output In A 2W Form Factor
Murata Power Solutions has introduced a new range of isolated single output dc-dc converters that it says 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 19.65 (0.774) x 7.65 (0.301) x 10.15mm (0.4in.), the MEV3 series is well 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 5 or 12V and single output voltages of 5, 9, 12 or 15V. All models in the range have a wide operating temperature range of -40 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 what is described as 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.
