Pin Function
Input power supplies. Powers the internal circuitry and is connected to the source of high-side P channel MOSFET.
Ground connection.
Enable pin. When connected to logic high or tied to VIN pin, the SC4626 is on. When connected to logic low, the
device enters shutdown and consumes less than 1μA of current. The enable pin has a 1 MΩ internal pulldown
resistor. This resistor is switched in circuit whenever the EN pin is below the enable input high threshold, or when
the part is in undervoltage lockout.
Output voltage sense pin.
Switching node - connect an inductor between this pin and the output capacitor.
