Absolute Maximum Ratings

IN, LX to PGND................................................ -0.3V to +17.6V

LX to PGND (less than 10ns) (Note 1) .. (VIN – 22)V to +22.0V

BST to LX........................................................... -0.3V to +2.0V

VL, POKB, SEL to AGND................................... -0.3V to +2.0V

EN to AGND..................................................... -0.3V to +17.6V

OUTS to AGND.................................................. -0.3V to +6.0V

PGND to AGND ..................................................-0.3V to +0.3V

Continuous Power Dissipation at TA = 70ºC (Derate

12.05mW/°C above +70°C) (Note 2) ...................... 963.70mW

Maximum Junction Temperature ...................................+150°C

Storage Temperature Range.......................... -65°C to +150°C

Soldering Temperature (Reflow) ...................................+260°C

Note 1: LX has internal clamp diodes to its corresponding PGND and IN. Applications that forward bias these diodes should not

exceed the ICs package power dissipation limits.

Note 2: Package thermal measurements were obtained using the method described in JEDEC specification JESD51-7, using a FR-

4, four-layer board. For detailed information on package thermal considerations, refer to

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.
