Pin Descriptions
Pin # Pin Name Pin Function
1
VIN
Input power supplies. Powers the internal circuitry and is connected to the source of high-side P channel MOSFET.
2
GND
Ground connection.
Enable pin. When connected to logic high or tied to VIN pin, the SC4626 is on. When connected to logic low, the
3
EN
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.
4
VOUT
Output voltage sense pin.
5
LX
Switching node - connect an inductor between this pin and the output capacitor.
