FUNCTION
Active-Low, Open-Drain Output. Indicates all outputs are ready. The on-resistance is 125
(typ).
2
FB
Main Boost Regulator Feedback Input. Regulates to 1.248V nominal. Connect feedback resistive
divider to analog ground (GND).
3
INTG
Main Boost Integrator Output. If used, connect 470pF to analog ground (GND). To disable integrator,
connect to REF.
4
IN
Supply Input. +2.7V to +5.5V input range. Bypass with a 0.1μF capacitor between IN and GND, as
close to the pins as possible.
5
GND
Analog Ground. Connect to power ground (PGND) underneath the IC.
6
REF
Internal Reference Bypass Terminal. Connect a 0.22μF capacitor from this terminal to analog ground
(GND). External load capability to 50μA.
7
FBP
Positive Charge-Pump Regulator Feedback Input. Regulates to 1.25V nominal. Connect feedback
resistive divider to analog ground (GND).
