※No voltage, no matter how instantaneous, shall be applied beyond the absolute maximum voltage rating to this product.
If you apply any voltage over this limit the product characteristics will deteriorate or the product itself will be destroyed.
Even though it may continue operating for a while after the over-voltage event, its life will likely be shortened significantly.
Reliability and life of the module may degrade similarly if the maximum operating voltage rating is continuously exceeded.
This product is designed to operate within the maximum operating voltage rating specification.

9.2.4. Remote On/Off Control
Start and halt is possible with a control signal.
While the control signal stops output from DC-DC converter, alarm output does not send any signal.
Start : RC is open or connected to-Vin.
Halt : RC is connected to +Vin.
9.2.5. Alarm Output
ALM pin is down to the same voltage level of-Vin pin and sends an alarm signal. (open-drain output)
Sink current in ALM pin is Max.10mA.
It is possible to halt all of the connected DC-DC converters when any one is halted with over voltage
protection or low voltage protection, with connecting all ALM pins for the application of
parallel/multiple operation with plural DC-DC converters.
The maximum number connecting DC-DC converters is 10pcs for the purpose of halting all DC-DC
converters connected with ALM pin each other.
Please contact us when more than 10pcs.
9.2.6. Synchronous Turn-on/off
It is possible to avoid the unevenness of turn-on timing with unifying the various Turn-on input
voltage to a certain voltage which one DC-DC converter has, and with connecting PO pins each
other for the application of parallel/multiple operation of plural DC-DC converters.
It is necessary to connect PO pins for parallel operation.
The maximum number connecting DC-DC converters is 10pcs for the purpose of synchronous
turn-on/off with connecting PO pins.
Please contact us when more than 10pcs.
