PRODUCT OVERVIEW

Offering conﬁgurable triple output voltages of +15V,

+5V and +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.

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?”

The MGJ3 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 MGJ3 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 MGJ3 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.
