Murata has announced the MGJ3 and MGJ6 series of configurable output voltage, high isolation DC-DC converters from Murata Power Solutions. These 3 Watt and 6 Watt surface mounted devices are optimized for use as high-side and low-side gate drivers in IGBT and MOSFET bridge circuit designs. Providing triple output voltages of +15, +5 and +5 VDC, these converters provide optimum switching of IGBT drives for best overall system efficiency. In addition, the outputs are configurable to suit a number of different circuit requirements such as +15 and -5 VDC or +20 and -5 VDC.
Both the MGJ3 3 Watt and the MGJ6 6 watt converters are available with a choice of wide input voltages around nominal +5, +12, or +24 VDC inputs. The input ranges are 4.5 to 9 VDC (+5 VDC nominal), 9 to 18 VDC (+12 VDC nominal) and 18 to 36 VDC (+24 VDC nominal).
The MGJ3 measures 23.11 x 22.61 x 14.65 mm and the MGJ6 is 31.24 x 22.61 x 14.65 mm. Both series can operate over the wide temperature range from -40 to +105°C. Short circuit and overload protection features ensure a robust operation during system fault conditions. Other control inputs include a disable pin to facilitate power saving and a frequency synchronization input that aids EMC filter design.
Typical applications for the MGJ series include use in motor drives, traction control drives, and wind turbine generators.
Lead-time is from stock to 10 weeks. Pricing in OEM quantities is US$11.20 for the MGJ3; for the MGJ6, US$14.70.
