ABSOLUTE MAXIMUM RATINGS
IN, FB, SHDN, ODI, ODO to GND ............................-0.3V to +6V
LX to GND (Note 1)......................................-0.3V to (VIN + 0.3V)
PGND to GND .......................................................-0.3V to +0.3V
LX Current ...........................................................................1.27A
Output Short Circuit to GND

Continuous Power Dissipation (TA = +70°C)
5-Pin Thin SOT23 (derate 9.1mW/°C above +70°C) ....727mW
8-Pin TDFN (derate 24.4mW/°C above +70°C) .........1951mW

Note 1: LX has internal clamp diodes to PGND (GND for MAX8560) and IN. Applications that forward bias these diodes should take
care not to exceed the IC’s package power-dissipation limits.
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
(VIN = 3.6V, SHDN = IN, TA = -40°C to +85°C, typical values are at TA = +25°C, unless otherwise noted.) (Note 1)
