The current sense input pin. This pin should be connected to Drain
node of the external PFET.
Signal ground.
No connection.
The feedback input. Connect the FB to a resistor voltage divider
between the output and GND for an adjustable output voltage.
Current limit threshold adjustment. It connects to an internal 5.5µA
current source. A resistor is connected between this pin and the input
Power Supply. The voltage across this resistor is compared with the
V
occurred.
Power ground.
Gate Drive output for the external PFET. PGATE swings between
V
Power supply input pin.
