ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are those values beyond which
the device could be permanently damaged. Absolute
maximum ratings are stress ratings only and functional
device operation is not implied.

Voltage on any other pin ..... GND – 0.3V to VOUT + 0.3V
Peak Switch Current (IPEAK) ......................................... 2A
Average Switch Current (IAVG) ..................................... 1A
Junction Temperature .............................................. 150ºC
Storage Temperature Range ...................... –65ºC to 150ºC
Lead Temperature (Soldering 10 sec) ...................... 260ºC
Thermal Resistance (qJA) .................................... 160ºC/W
