Murata Power Solutions MGJ1 Series

MGJ1 series of DC-DC converters

The MGJ1 series of DC-DC converters is ideal for powering ‘high side’ and ‘low side’ gate drive circuits for IGBTs and MOSFETS in bridge circuits. A choice of asymmetric output voltages allows optimum drive levels for best system efficiency. The MGJ1 series is characterised for high isolation requirements commonly seen in bridge circuits used in motor drives and inverters, while the MGJ1 industrial grade temperature rating and construction gives long service life and reliability.
