5. Output−V
6. Stand−by SW function
In case of such abnormalities as output−V
inform the abnormal state to the outside by turning a NPN transistor is turned on.
It is possible to improve the reliability of not only power IC but also an entire equipment by (1) display by LED
and LCD and (2) by turning the power supply relay off.
By means of controlling pin(1) (stand−by terminal) to high and low, the power supply can be set to on and off.
The threshold voltage of pin(1) is set at about 3V
(typ.) at the stand−by state.
