Pin Description

Pin Number

Pin Name

Pin Function

1, 13

VIN

Drain of internal MOSFET, Pin 1 must connect to Pin 13.

2

EN

Active-high digital input used to turn on the MOSFET, pin has an internal pulldown resistor to GND.

3

VCC

Supply voltage to controller (3.0V to 5.5V).

4

GND

Controller ground.

5

SR

Slew rate adjustment; Please refer to CSR vs. VOUT rising time table.

6

PG

Active-high, open-drain output that indicates when the gate of the MOSFET is fully charged, external

pullup resistor

 1kΩ to an external voltage source required; tie to GND if not used.

7

BLEED

Load bleed connection, must be tied to VOUT either directly or through a resistor  1kΩ.

8 to 12

VOUT

Source of internal MOSFET connected to load.
