*: Pin 5 is the ON/OFF pin. Soft start at power on can be performed with a capacitor connected to

this pin.

SI-8000JD

The output can also be turned ON/OFF with this pin.

The output is stopped by setting the voltage of this pin to V^SSLor lower.

ON/OFF-pin voltage can be changed with an open-collector drive circuit of a transistor.

When using both the soft-start and ON/OFF functions together, the discharge current from C³

flows into the ON/OFF control transistor. Therefore, limit the current securely to protect the

transistor if C³capacitance is large.

ON/OFF

The ON/OFF pin is pulled up to the power supply in the IC, so applying the external voltage is

prohibited.
