VP
Input power pin; connected to the source of the P-channel MOSFET.
Connect a 2.2μF or larger capacitor from these pins to PGND.
IC active high enable pin. Alternative input pin for S
2
Cwire control uti-
lizing FB2 reference.
Logic high selects FB1 high output reference; logic low selects FB2 low
output reference. Pull low for S
2
Cwire control. See Tables 1 and 2.
Input voltage for the converter. Connect this pin directly to the VP pin.
No connection. Do not make any connection to this pin.
Boost converter switching node. Connect the power inductor between
the SW pin and the LIN pin.
Power ground for the boost converter; connected to the source of the
internal N-channel MOSFET. Connect input and output capacitor
returns to PGND.
Ground pin.
Feedback pin for low output voltage set point. Pin set to 0.6V when
SEL is low and disabled when SEL is high. Voltage is set from 0.6V to
1.2V using S
2
Cwire control.
Feedback pin for high output voltage set point. Pin set to 1.2V when
SEL is high and disabled when SEL is low. Disabled with S
2
Cwire
control.
Switched power input. Connected to the power inductor.
Exposed paddle (bottom). Internally connected to SW. May be exter-
nally connected to SW pins or left floating. Do not connect to GND
or PGND.
