PRODUCT OVERVIEW
The MGJ1 series of DC-DC converters is ideal
for powering ‘high side’ and ‘low side’ gate drive
circuits for IGBTs/SiC 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.
