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.

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
SAFETY APPROVAL
ANSI/AAMI ES60601-1
The MGJ2 series has been recognised by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 1 MOOP (Means Of Operator Protection) based on a working voltage
of 300Vrms or 2 MOOP based upon a working voltage of 200 Vrms, and 1 MOPP (Mean Of Patient Protection) based on a working voltage of 200Vrms., between Primary and
Secondary. The MGJ2D241709SC is currently pending recognition.
File number E202895 applies.
UL 60950
The MGJ2 series is recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 150Vrms and for basic/supplementary insulation to a
working voltage of 300Vrms. The MGJ2D241709SC is currently pending recognition.
File number E151252 applies.
Creepage and clearance 3mm.
Fusing
The MGJ2 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.
MGJ2x05xxxC: 1.25A
MGJ2x12xxxC: 750mA
MGJ2x15xxxC: 750mA
MGJ2x24xxxC: 750mA
All fuses should be UL recognized and rated to 125V.
RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260ºC for 10 seconds. The pin termination finish
on this product series is Tin Plate, Hot Dipped over Matte Tin with Nickel Preplate. The series is backward compatible with Sn/Pb soldering
systems. For further information, please visit www.murata-ps.com/rohs

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%.
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
series will start into capacitance ranging from 47µF up to 220µF with increased start times.
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.
