Pin Function Description
VIN (Pin 1)
Input supply voltage for dual-mode application. Con-
nect a schokkty diode (current rating >500mA) to USB
port or 5V adapter. If the LDO mode is not used, tie
the VIN pin to ground.
FB (pin 2)
Internal 1.2V reference voltage. Connect to OUT for 3.
3V output,. Connect to GND for 2.5V output. Use a
resistor divider to set the output voltage from 2.5V to
5.5V.
SHDN (pin 3)
Shutdown input. High = operating mode; Low = shut-
down mode.
LBI (Pin 4)
Low-battery comparator input. Internally set to trip at
0.6V.
LBO (pin 5)
Open-drain low battery comparator output. Connect
LBO to OUT through a 100K
resistor. Output is low
as V
LBI
< 0.6V. Open-drain device is turned on during
shutdown.
OUT (pin 8)
Power output. OUT provides bootstrap power to the
IC.
GND (Pin 6)
Ground pins of the circuitry and all ground pins must
be soldered to PCB with proper power dissipation.
LX (pin 7)
N-channel and P-channel power MOSFET drain
connection.
