PRODUCT OVERVIEW
The MGJ2 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
and EMI. The MGJ2 series is characterised for high
isolation and dv/dt requirements commonly seen in
bridge circuits used in motor drives and inverters,
while the MGJ2 industrial grade temperature
rating and construction gives long service life and
reliability.
