ABSOLUTE MAXIMUM RATINGS
LX, Vo, V BATT , LBON, FB to GND pin ................................ -0.3 to 6.0V
SHDN, LBI ........................................................... -0.3V to V BATT +1.0V
Vo, GND, LX Current ....................................................................... 2A
Reverse V BATT Current .............................................................. 220mA
Forward V BATT Current .............................................................. 500mA
Storage Temperature .................................................. -65 ° C to 150 ° C
Operating Temperature ................................................ -40 ° C to +85 ° C
ESD Rating ........................................................................ 1.5kV HBM
These are stress ratings only and functional operation of the device at
these ratings or any other above those indicated in the operation sections
of the specifications below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect reliability.
ELECTRICAL SPECIFICATIONS
V BATT =V SHDN = 2.6V, V FB =0.0V, I LOAD = 0mA, T AMB = -40 ° C to +85 ° C, V OUT = +3.3V, typical values at 27 ° C unless
otherwise noted. The ? denotes the specifications which apply over full operating temperature range -40 ° C to +85 ° C, unless
otherwise specified.
