Input voltage pin
*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. Although pins of number 1 and 2 are connected internally, be sure to short-circuit them nearest in use.
*3. The NC pin is electrically open.
The NC pin can be connected to the VIN pin or the VSS pin.
*4. 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.
