PRODUCT OVERVIEW
Offering configurable triple output voltages of +15V,
+5V and +5V, the MGJ6 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 MGJ6 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 MGJ6 protection features
include short circuit protection, over temperature
protection and overload protection.

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 MGJ6 series of DC/DC converters are all 100% production tested at their stated isolation voltage. This is 5.2kVDC for 1 second.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
The MGJ6 series is pending recognition by Underwiters 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.
SAFETY APPROVAL
UL 60601
The MGJ6 series is pending recognition by Underwriters Laboratory (UL) to the 3rd edition of 60601 and provides 1 MOOP (means of operator protection) based upon a working
voltage of 250 Vrms max., between Primary and Secondary.
UL 60950
The MGJ6 series is pending recognition by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms.
CHARACTERISATION TEST METHODS
Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1 1µF X7R m ultilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter
C2 10µF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC/DC converter with an ESR of less
than 100m at 100 kHz
C3 100nF multilayer ceramic capacitor, general purpose
R1 450 resistor, carbon film, ±1% tolerance
R2 50 BNC termination
T1 3T of the coax cable through a ferrite toroid
RLOAD Resistive load to the maximum power rating of the DC/DC converter. Connections should be made via twisted wires
Measured values are multiplied by 10 to obtain the specified values.
