Enclosed DC/DC converter MGJ3 series

step-downgate driverfor IGBT

Offering configurable dual output voltages of +15V/-10V, +20V/-5V and +15V/-5V, the MGJ3 series of DC-DC converters are ideal for powering ‘high side’ and ‘low side’ gate drive circuits for IGBTs, Silicon Carbide and Mosfets in bridge circuits. A choice of asymmetric output voltages allows optimum drive levels for best system efficiency and EMI. The MGJ3 series is characterised for high isolation and dv/dt requirements commonly seen in bridge circuits used in motor drives and inverters. A disable/frequency synchronisation pin, simplifies EMC filter design. The MGJ3 protection features include short circuit protection, over temperature protection and overload protection.
