SC4626

Pin Descriptions

Pin #

Pin Name

Pin Function



VIN

Input power supplies. Powers the internal circuitry and is connected to the source of high-side P channel MOSFET.

2

GND

Ground connection.

3

EN

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 µA of current. The enable pin has a  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.
