PIN FUNCTIONS

XSHD (Pin 1)

XSHD is the logic controlled shutdown input pin. When

XSHD is low, the IC is shutdown and it’s quiescent current is

less than 1 µA. When XSHD is high, the IC is working in

normal operation.

VIN (Pin 2)

VIN is the pin connected to battery input voltage. The IC gets

its power supply from VIN.

FB (Pin 3)

FB is the feedback pin of the output voltage via resistor

divider. FB is about 0.3 V and its difference from 0.3 V

reference voltage is amplified by the error amplifier.

AGND (Pin 4)

AGND is the pin for ground of controlling circuit.

PGND (Pin 5)

PGND is the pin for ground of the internal power MOS driver.

EXT (Pin 6)

EXT is the output pin of internal driver. It’s connected to the

gate of external power MOSFET.
