105°C operating temperature
Offering configurable dual output voltages of +15V/10V, +20V/-5V and +15V/-5V, the MGJ3 series of
DC-DC converters is ideal for powering ‘high side’
and ‘low side’ gate drive circuits for IGBTs, Silicon
and Silicon Carbide 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 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 MGJ3 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?”
When the insulation in the MGJ3 series is not used as a safety barrier , i.e. provides functional isolation only, continuous or switched voltages across the barrier up to
3kV are sustainable. Long term reliability testing at these voltages continues. Peak Inception voltages measured were in excess of 3.5kV when testing for partial discharge in accordance with IEC 60270. Please contact Murata for further information.
The MGJ3 series has been recognized by Underwiters Laboratory to 250 Vrms Reinforced Insulation, 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
ANSI/AAMI ES60601-1
The MGJ3 series is pending recognition ANSI/AAMI ES60601-1.
UL 60950
The MGJ3 series has been recognized by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms with a maximum measured product
operating temperature of 105°C.
Creepage and clearance 7mm.
FUSING
The MGJ3 Series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below.
Input Voltage, 5V 2A
Input Voltage, 12V 1A
Input Voltage, 24V 0.5A
All fuses should be UL recognized, 125V rated.
CHARACTERISATION TEST METHODS
Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1
1μF X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter
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
C2
than 100mΩ at 100 kHz
C3
100nF multilayer ceramic capacitor, general purpose
R1
450Ω resistor, carbon film, ±1% tolerance
R2
50Ω 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.
