1-Cell to 2-Cell, Low-Noise,
High-Efficiency, Step-Up DC-DC Converter
ABSOLUTE MAXIMUM RATINGS
BATT, OUT,LX, SHDN to GND ..............................-0.3V to +6.0V
OUT, LX Current.......................................................................1A
FB, PFI, PFO to GND ................................-0.3V to (V OUT + 0.3V)
Reverse Battery Current (T A = +25°C) (Note 1) ...............220mA
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature ......................................................+150°C
Storage Temperature Range .............................-65°C to +165°C
Lead Temperature (soldering, 10sec) .............................+300°C
Continuous Power Dissipation (T A = +70°C)
μMAX (derate 4.1mW/°C above +70°C) .......................330mW
Note 1: The reverse battery current is measured from the Typical Operating Circuit’s input terminal to GND when the battery is con-
nected backward. A reverse current of 220mA will not exceed package dissipation limits but, if left for an extended time
(more than 10 minutes), may degrade performance.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(V BATT = V SHDN = 1.3V, I LOAD = 0, FB = GND, T A = 0°C to +85°C , unless otherwise noted. Typical values are at T A = +25°C.)
