*1. Connect the heat sink of backside at shadowed area to the board, and set electric potential open or GND.
However, do not use it as the function of electrode.
*2. The NC pin is electrically open.
The NC pin can be connected to the VIN pin or the VSS pin.
*3. Connect a capacitor between the SSC pin and the VSS pin.
The soft-start time at power-on and at the time when the ON / OFF pin is set to ON can be adjusted according to
the capacitance.
