Murata to start mass production of 200-W DC-DC converter for advanced electric scooter

September 25, 2013 // By Paul Buckley
Murata plans to commence mass production of a dual output non-isolated DC-DC converter designed specifically for electric scooter applications in February 2014.

The high efficiency 200 Watt MPD7K046 converter accepts an input voltage in the range of +36 to + 60 VDC around a nominal +48 VDC. The primary output provides +12 VDC at a continuous rating of 10 A, and up to 18 A peak current. The secondary output delivers a +5 VDC / 1 A supply that suits logic rails and as a USB supply. Energy efficiency is typically 95%.

Murata customer, Terra Motors, has recently selected the MPD7K046 for its new A4000i electric scooter. The converter will enable power from the scooter’s battery to be used for auxiliary equipment such as headlights by stepping it down from +48 to +12 VDC.

The A4000i is believed to be the world’s first electric scooter with a smartphone connection.
