Soft start at power on can be performed with a capacitor connected to this pin. The output can also be turned ON/OFF with this pin. SI-8000JD SI-8000JD SI-8000JD The output is stopped by setting the voltage of this pin to VSSL or lower. ON/OFF-pin voltage can be changed with an open-collector drive circuit of a transistor. 5 ON/OFF 5 ON/OFF 5 ON/OFF 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 C3 C3 transistor if C3 capacitance is large. The ON/OFF pin is pulled up to the power supply in the IC, so applying the external voltage is prohibited. VOUT. ON/OFF Soft Start Soft Start +VOUT. ON/OFF 16 ICs
