Value

Input Voltage (VVIN1, VVIN2, VVIN3, VVCC)

-0.3V to +6.5V

SW Pin Voltage (VLX1, VLX2, VLX3)

-0.3V to VVINX+0.3V

All Other Pins Voltage

-0.3V to +6.5V

Ambient Temperature operating Range (TA)

-40°C to +85°C

Maximum Junction Temperature (TJmax)

+150°C

Lead Temperature (Soldering, 10 sec)

+260°C

Storage Temperature Range (TS)

-65°C to +150°C

Note (1):Stresses beyond those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device.

Exposure to “Absolute Maximum Ratings” conditions for extended periods may affect device reliability and

lifetime.
