Pin Function
Enable control input. Connect this pin to logic high can enable the device and
connect this pin to GND can disable the device.
Power ground. The exposed pad must be soldered to a large PCB and connected
to PGND for maximum power dissipation.
Analog ground. Should be electrically connected to GND close to the device.
Feedback voltage input. Connect this pin to the midpoint of the external feedback
resistive divider to set the output voltage of the converter to the desired regulation
level. The device regulates the FB voltage at Feedback Reference Voltage,
typically 0.45V.
Output voltage sense pin for the internal control loop. Must be connected to
output.
Power good open-drain output. This pin is pulled to low if the output voltage is
below regulation limits. Can be left floating if not used.
Switch node. The Source of the internal high-side power MOSFET, and Drain of
the internal low-side (synchronous) rectifier MOSFET.
Power input supply voltage, 2.5V to 5.5V.
