Pin Description
1
FB
Output Voltage Feedback Input.
2
LBI
Low–Battery Detector Input.
3
LBO
Open–Drain Low–Battery Detector Output. Output is LOW when V
LBI
is
impedance during shutdown.
1.178 V. LBO is high
4
REF
1.190 V Reference Voltage Output, bypass with 150 nF capacitor if this pin is not loaded, bypass with
1.0 F if this pin is loaded up to 2.5 mA @ V
OUT
= 3.3 V.
5
SHDN
Shutdown Input. HIGH (
0.6 V) = operating; LOW (
0.3 V) = shutdown.
6
GND
Ground.
7
LX
N–Channel and P–Channel Power MOSFET Drain Connection.
8
OUT
Power Output. OUT provides bootstrap power to the IC.
