Stand-by SW Function (pin 6)
By means of controlling pin 6 (stand-by terminal) to
High and Low, the power supply can be set to ON and
OFF.
The threshold voltage of pin 6 is set at about 3 VBE
(typ.), and the Power Supply current is about 1 A
(typ.) at the stand-by state.

(1)
Since VCC can directly be controlled to ON or OFF by the microcomputer, the switching relay can be
omitted.
(2)
Since the control current is microscopic, the switching relay of small current capacity is satisfactory
for switching
