*3: Pin 6 and pin 11 are the SS pins. Soft start at power on can be performed with capacitors connected to these pins. The outputs can also be turned ON/OFF with these pins. The
outputs are stopped by setting the voltages of these pins to V
SSL
or lower. SS-pin voltages can be changed with open-collector drive circuits of transistors.
When using both the soft-start and ON/OFF functions together, the discharge currents from C
4
and C
5
flow into the ON/OFF control transistors respectively. Therefore, limit the
currents securely to protect the transistors if C
4
and C
5
capacitances are large. The SS pins are pulled up to the power supply in the ICs, so applying the external voltages are
prohibited.
