MPD7D05*S Application
5
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 for Multiple operation,
: 5pcs for parallel operation of identical output voltage of this TF50A.
It is NOT possible in using other DC-DC Converters with this TF50A for parallel.
To connect more than the above-stated-number, 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 5 devices of the same this model in parallel operation.
This series are NOT applicable for parallel operation with other 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.
