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.

TECHNICAL NOTES
ISOLATION VOLTAGE
‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test
voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Murata Power Solutions MGJ2 series of DC-DC converters are all 100% production tested at 5.2kVDC for 1 second and have been qualification tested at 5.2kVDC for 1
minute.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
When the insulation in the MGJ2 series is not used as a safety barrier , i.e. provides functional isolation only, continuous or switched voltages across the barrier in excess
of 1.5kV are sustainable. Long term reliability testing at these voltages continues. Please contact Murata for further information.
The MGJ2 series
is recognised by
Underwriters Laboratory for various voltages, please see safety approval section below.
REPEATED HIGH-VOLTAGE ISOLATION TESTING
It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on
materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be
reduced by 20% from specified test voltage.

APPLICATION NOTES
Minimum load
The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading will result in
an increase in output voltage, which may rise to typically 1.25 times the specified output voltage if the output load falls to less than 5%.
Gate Drive Applications Advisory Note
For general guidence for product usage in gate drive applications please refer to
“gate drive application notes”.
Capacitive loading and start up
Typical start up times for this series, with a typical input voltage rise time of 2.2μs and output capacitance of 10μF, are shown in the table below. The product
