PRODUCT OVERVIEW
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 5.2kVDC for 1 second and 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 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 dis-
charge in accordance with IEC 60270. Please contact Murata for further information.
The MGJ3 series has been recognised by Underwriters 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 recognised to ANSI/AAMI ES60601-1 and provides 1 MOPP (Means Of Patient Protection) and 2 MOOP (Means Of Operator Protection) based upon a working
voltage of 250 Vrms max, between Primary and Secondary.
UL 60950
The MGJ3 series has been recognised 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 recognised, 125V rated.
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.

The Disable/Synchronization pin has three modes:
1. When a DC logic low voltage is applied to this pin the MGJ3 is disabled and enters a low quiescent current sleep mode.
2. When this pin is left floating or a DC logic high (CMOS/TTL compatible) voltage is applied the MGJ3 is enabled and operates at the programmed frequency of 100kHz.
3. When a square wave of between 90kHz and 110kHz is applied to this pin, the switcher operates at the same frequency as the square wave. The falling edge of the
square wave corresponds to the start of the switching cycle. If the signal is slower than 25Hz, it will be interpreted as enabling and disabling the part. If the MGJ3 is
disabled, it must be disabled for 7 clock cycles before being re-enabled.
Note: The DIS/Sync pin is a high impedance TTL input and can be triggered by noise from external circuits if not treated carefully. It is advised that any pcb traces
connected to the DIS/Sync pin are kept as short as possible and away from other noisy pcb traces. The track should follow a similar route to the return path to avoid
differential noise pick up. If the pin is not used for synchronisation then a 22nF capacitor can be added from DIS/Sync pin to –Vin to suppress noise.

The following filter circuit and filter table shows the input filters typically required to meet EN55022 Quasi-Peak Curve A or B. If a high dv/dt above 80kV/us is expected from
output to input it is advised that a common mode filter is used on the input without Y capacitors. This will reduce the common mode current and reduce interference with
primary side circuits.
