Pin #
Symbol
Function
1, 2
LIN
Switched power input. Connect to the power inductor.
3
FB1
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 S2Cwire control. Tie directly to FB2 pin for
static (fixed) output voltage.
4
FB2
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 with S2Cwire control. Tie
directly to FB1 pin for static (fixed) output voltage.
5
GND
Ground pin.
6, 7, 8
PGND
Power ground for the boost converter; connected to the source of the N-channel MOSFET.
Connect to the input and output capacitor return.
9, 10
SW
Boost converter switching node. Connect the power inductor between this pin and the
LIN pin.
11
N/C
No connection.
12
VIN
Input voltage for the converter. Connect this pin directly to the VP pin.
13
SEL
Logic high selects FB1 high output reference. Logic low selects FB2 low output reference.
Pull low for S2Cwire control.
14
EN/SET
Active high enable pin. Alternately, input pin for S2Cwire control using the FB2 reference.
15, 16
VP
Input power pin; connected internally to the source of the P-channel MOSFET. Connect
externally to the input capacitor(s).
EP
Exposed paddle (bottom). Connected internally to the SW pins. Can be tied to bottom
side PCB heat sink to optimize thermal performance.
