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 MGJ6-3P series of DC-DC converters are all 100% production tested at 4kVACrms for 1 second from input to output and 2.5kVACrms for 1
second from output to output. Also they are all qualification tested at 5.7kVDC for 1 minute from input to output and 3kVDC for 1 minute from output to output.
The MGJ6-3P series is recognised by Underwriters Laboratory, please see safety approval section for more information. When the insulation in the MGJ6-3P 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. This is established by
measuring the partial discharge Inception voltage in accordance with IEC 60270. Please contact Murata for further information.
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 MGJ6-3P series is recognised by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 2 MOPP (Means Of Patient Protection) based on a working

When a DC logic low voltage is applied to this pin the MGJ6-3P is disabled and enters a low quiescent current sleep mode.
When this pin is left floating or a DC logic high (CMOS/TTL compatible) voltage is applied the MGJ6-3P is enabled and operates at the programmed frequency of
100kHz.
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
MGJ6-3P 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.
Please refer to “LAYOUT CONSIDERATIONS” and “SYNCHRONISATION CIRCUIT” for further details.
Click here for general guidance for gate drive applications.
Layout considerations
Unlike standard isolated DC-DC products the MGJ6-3P series has been designed specifically for high side gate drive applications where the outputs are being driven to a
high voltage at a very high dV/dT. This is possible due to minimum transformer isolation capacitance and considered circuit design regarding common mode transient immunity. It is important that these few simple pcb layout guidelines are implemented so as not to compromise the performance of the DC-DC and that of the overall system.
1.
The keep clear area shown must not have any copper traces even on internal layers. This is not only to avoid compromising the creepage and clearance distance but
also to minimise capacitive isolation between the noisy output circuits and input control circuits. In general it is good practice to maintain the same band of clearance
area running directly through both the DC-DC and the gate drive isolators as shown so that input and output are kept separate and do not overlap or mesh together
at any point.
2.
A top layer ground plane copper area connected to –Vin can be used to create an effective screen to the underside of the MGJ6-3P series and can also be used as a
guard ring for the gate drive isolator inputs. If the Dis/Synch pin is being used then it is imperative that it follows a route covered by this screen to avoid differential
pick up. It should also be kept as short as possible.
Please refer to “PACKAGE SPECIFICATIONS” for recommended layout.

1.
A suggested synchronisation circuit is shown. C1 and C2 are 100nF capacitors. D1 and D2 are schottky diodes. The capacitive isolation and close connected diode
ensures that a transition from high to low is seen at the input pin even in a noisy environment or when there is a slight ground shift between devices.
2.
If the Dis/Sync pin is not used for synchronisation, then a 22nF capacitor can be added between the Dis/Sync pin and –Vin pin to improve noise immunity. If the
functionality of Dis/Sync is not required, the Dis/Sync pin can be connected directly to the +Vin pin to improve noise immunity.
3.
One very effective method to reduce common mode transient interference is to add a common mode filter to the DC input. It may only be necessary to add one
before splitting the supply to each DC-DC.

For some high frequency applications where each low side device has a kelvin sense terminal or it is necessary to connect the gate drive supply as close to the device
terminal as possible the following circuit can be used. By adding 10Ohm resistors in the positive and negative gate supply lines to each gate drive circuit it is possible to
create a high frequency separation between the supplies. This means it is possible to significantly reduce the emitter inductance in the gate driving loop without the need
for separate isolated supplies.

For three phase drives on an Electric Vehicle system it is sometimes necessary, for safety and diagnostic reasons to power the high side switches independently to the Low
side switches. This means that if a fault occurs on a the high side switch it is possible to disable all of the high side switches without disabling the low side switches. In
this case it is recommended that two full bridge MGJ6 units are used. The circuit below shows how two full bridge MGJ6 units can be connected to achieve this, for more
information on the full bridge MGJ6 series please refer to the datasheet.

For convenience the four isolated 24V outputs have been labelled VHA (Voltage A for high side), VHB (Voltage B for high side), VHC (Voltage C for high side) and VL (Voltage
for low side) however they can be swapped if this helps to improve system layout. It is recommended however that if VHA, VHB or VHC are used in place of VL that an additional 4.7uF ceramic capacitor is added close to the output pins to reduce ripple voltage.
Any output can be connected in parallel with another and all three outputs can also be connected in series with one another. With the possibility of series and parallel
output connections a number of output configurations are possible. Some are shown below:
A) 24V @ 0.25A
B) 96V @ 0.063A output
C) +24V/-48V @ 0.063A
D) +/-48V @ 0.063A
Note: Any single 24V output can deliver up to 3W however the
E) Non-isolated +12V to +108V boost converter @0.063A
F) Non-isolated +24V to +120V boost converter @0.063A
output power from all outputs combined must not exceed 6W

APPLICATION NOTES (Continued)
SLIC Circuits
Power source is preferred to the telephone system power due to either the power quality of the telecommunications system power supply or to avoid potential power
line disturbances, such as lightning strikes and access switching, which will affect the target circuit function.
Another application area is in fibre-in-the-loop (FITL) or radio-in-the-loop (RITL) interfacing via a standard telecommunication SLIC, where the usual telecommunication
battery voltage is not available due to the transmission media in use (fibre or radio). In particular, FITL/RITL interfaces directly on PC cards, in local monitor and boost
circuits and at exchanges between the fibre/radio and wire media. The supply rails can be used for ringing generators as well as SLIC circuits or where both are combined, such as in the AMD AM79R79 Ringing SLIC device (see figure 2). The -72V rail is used primarily for the generation of the ringing signal (VBAT1), the -48V rail is
used to supply in line access circuitry (VBAT2) and the -24V supply for the on-chip regulator for the logic interface (VNEG). Alternative devices from other manufacturers
could use the +/-24V outputs for their internal circuit supply and -72V for ringing.

EMC FILTERING AND SPECTRA
FILTERING
The following filter circuit and filter table shows the input filters typically required to meet conducted emissions limits for EN 55022 curve B using Quasi-Peak (pink line) and
average (green line) detectors according to CISPR22. The following plots show measurements of the positive (L1) and negative (L2) inputs for both Quasi-peak limit B adherence and Average limit B adherence. 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 each output as this will
reduce the common mode current circulating between outputs and input and causing interference.
