6Watt BLC05 Series
7. Various functions
7-1 ON/OFF control
The ON/OFF control function enables users to control ON/OFF of the output voltage without inputting or
cutting it off.
Between –Vin terminal (No. 2 pin) and ON/OFF terminal (No. 3 pin)
Open (6V max.)
Short (0 to 0.5V, 4mA max.)

7-2 Output over current protection
If output current has reached over current status, the over current protection circuit is activated lowering
the output voltage. (Activating point: 105% or above of the rated load current)
The converter should automatically return to normal operation as soon as the over current status is
resolved, if this does not occur, turn off the power or turn the output OFF with an ON/OFF control and
then reactivate.
Holding of over current status for over 30 seconds may result in damage, so resolve over current status
within 30 seconds.

Note) A drooping characteristic may be seen in
the over current protection state as shown on
the left figure. Note that output voltage may not
go up if connected to a nonlinear load such as a
lamp, motor, etc., or a constant current load.
