5 Operation Information
5 .1 Reset Condition
In order to reset all functions, the input voltage (Vin) must be set under 5V for 1s. min.
Vin 36 to 75V
Reset Condition
5V min
1s.min
5 .2 Over Voltage Protection (OVP)
The Isolated DC-DC Converter enters latch-up mode after typical 0.5ms. mask time, when the output voltage
is over the value specified in Over Voltage Protection (section 8.1.2) by failure of internal control circuit.
In order to reset, the input voltage must be set under 5V for 1s. min.
Output voltage might exceed the point at which OVP starts to function under conditions of transient input
voltage or output current changes.
Therefore, OVP is set to wait for the mask time 0.5ms.
It is recommended to evaluate your appliances installed with the DC-DC Converter.
Vin 36 to 75V
Reset Condition
5V min
1s.min
5 .3 Low Voltage Protection (LVP)
The Isolated DC-DC Converter enters latch-up mode after typical 500ms. mask time, when the output voltage
is under the value specified in Low Voltage
Protection (section 8.1.2) by operating Over Current-limit Inception due to failure of internal control or over load.
In order to reset, the input voltage must be set under 5V for 1s. min.

5 .4 Remote On/Off Control
The connection to a RC pin controls an Isolated DC-DC Converter to turn on/off.
While the Isolated DC-DC Converter is halted via the remote control feature, the alarm function will not
operate; refer to Alarm Output (section 5-5).
Start
: RC open or connected to –Vin
Halt
: RC connected to +Vin
5 .5 Alarm Output (ALM)
The Alarm Output can be down to the level of -Vin (Open Drain Output), when Over Voltage Protection or
Low Voltage Protection features are activated. The sink current in ALM pin is 10mA max. Multiple Isolated
DC-DC Converters running independently and / or in parallel operation can be simultaneously halted by
connecting all ALM pins, when the Over Voltage Protection or Low Voltage Protection functions are activated
by any single DC-DC Converter. The maximum number connected running DC-DC Converters is 10pcs.
To connect more than 10,please consult Murata.
5 .6 Synchronous Turn-on/off
Multiple Isolated DC-DC Converters running independently and / or in parallel operation can be
synchronously toggled on & off timing among the running converters, of which the input voltage detection
circuits are tied to the detection voltage of a single reference Isolated DC-DC Converter. Every PO pin must
be connected for multiple and/or parallel operation.
The Maximum number connected running DC-DC Converters is 10pcs.
It is possible in using other DC-DC Converters with other MPD6D***S or MPD7 D***S series for multiple
and/or parallel operation.
For more detailed information, please consult Murata.
6 Parallel Operation
6 .1 Parallel Operation Description (Current sharing)
When the output current required is more than that available from one DC-DC Converter an alternative rather
than choosing a higher power rated DC-DC Converter is to operate multiple DC-DC Converters in parallel.
It is possible to run up to 10pcs in parallel operation.
This series are applicable for parallel operation with other MPD6D***S or
MPD7 D***S series.
PO pins should be connected so that the turn-on / off of all connected DC-DC Converters are synchronized.
Additionally connecting the ALM pins of the devices in parallel operation enables simultaneous shut down of
all DC-DC Converters when one is halted and generates an ALM signal due to an OVP or LVP condition.
6 .2 Load Balance in Parallel Operation
Neither external load balancing circuit nor reverse-current prevention circuit is necessary for Murata’s
DC-DC Converters operating in parallel. Murata’s DC-DC Converters are designed to regulate load balancing
and prevent reverse-current.
The combined devices operated in parallel provide an output voltage within the tolerance specified for either
device (e.g. +5% / -3%). This tolerance is maintained throughout the output current variance from zero to the
rated current value. This feature automatically balances the output currents from all of the parallel DC-DC
Converters
