1
PVIN
Input power pin; connected to the source of the P-channel MOSFET. Connect to the
input capacitor(s).
IC enable pin and S
2
Cwire input control to set output current.
FB voltage range select.
For the AAT1231, a logic LOW sets the FB voltage range from 0.1V to 0.4V; a logic
HIGH sets the FB voltage range from 0.3V to 0.6V.
For the AAT1231-1, a logic LOW sets the FB voltage range from 0.4V to 0.1V; a logic
HIGH sets the FB voltage range from 0.6V to 0.3V.
Input voltage for the converter. Connect directly to the PVIN pin.
No connection.
Boost converter switching node. Connect the power inductor between this pin and LIN.
Power ground for the boost converter.
Ground pin.
Feedback pin. Connect a resistor to ground to set the maximum LED current.
Feedback pin for over-voltage protection sense.
Switched power input. Connect the power inductor between this pin and SW.
