FB
Main Step-Up Regulator Feedback Input. Regulates to 1.25V
nominal. Connect a resistive divider from the output (V
MAIN
) to FB
to analog ground (GND).

INTG
Main Step-Up Integrator Output. When using the integrator,
connect 1000pF to analog ground (GND). To disable the
integrator, connect INTG to REF.

IN
Main Supply Voltage. The supply voltage powers the control
circuitry for all of the regulators and may range from 2.7V to 5.5V.
Bypass with a 0.1μF capacitor between IN and GND, as close to
the pins as possible.

BUF+
VCOM Buffer (Operational Transconductance Amplifier) Positive
Feedback Input. Connect to GND to select the internal resistive
divider that sets the positive input to half the amplifier

REF
Internal Reference Bypass Terminal. Connect a 0.22μF ceramic
capacitor from REF to analog ground (GND). External load
capability up to 50μA.

FBP
Positive Charge-Pump Regulator Feedback Input. Regulates to
1.25V nominal. Connect a resistive divider from the positive
charge-pump output (V
POS
) to FBP to analog ground (GND).
11

FBN
Negative Charge-Pump Regulator Feedback Input. Regulates to
0V nominal. Connect a resistive divider from the negative charge-
pump output (V
NEG
) to FBN to the reference (REF).

SHDN
Active-Low Shutdown Control Input. Pull
SHDN
low to force the
controller into shutdown. If unused, connect
SHDN
to IN for normal
operation. A rising edge on
SHDN
clears the fault latch.
13

SUPL
Low-Dropout Linear Regulator Input Voltage. Can range from 4.5V
to 15V. Bypass with a 1μF capacitor to GND (see
Capacitor
Selection and Regulator Stability
). Connect both input pins
together externally.
