Configurable output voltage high-isolation SMD DC-DC converters

Murata's MGJ3 and MGJ6 series of configurable output voltage high-isolation surface-mount DC-DC converters are now available from Farnell element14. They are optimised for use as high-side and low-side gate drivers in IGBT and MOSFET bridge circuit designs. The devices provide triple output voltages of +15, +5 and +5VDC, with optimum switching of IGBT drives for best overall system efficiency. The outputs are configurable to suit a number of different circuit requirements such as +15 and -5VDC or +20 and -5VDC. Both converters are available with a choice of wide input voltages around nominal +5, +12, or +24VDC inputs. The input ranges are 4.5 to 9VDC (+5VDC nominal), 9 to 18VDC (+12VDC nominal) and 18 to 36VDC (+24VDC nominal).
