C2 – (Pin 8): Flying Capacitor 2 Negative Terminal (C2).
OUT2 (Pin 9): Regulated Output Voltage 2. OUT2 is
disconnected from V IN when in shutdown. Bypass OUT2
with a low ESR ceramic capacitor to GND (C O2 ). See
Output Capacitor Selection section for size requirements.
C2 + (Pin 10): Flying Capacitor 2 Positive Terminal (C2).

EN2 (Pin 11): Input Enable Pin 2. When EN2 is high, OUT2
is enabled. When EN2 is low OUT2 is shut down.
FB2 (Pin 12): Feedback Input Pin 2. An output divider
should be connected from OUT2 to FB2 to program the
output voltage.
