Absolute Maximum Ratings(at TA=25°C) (Note 4)

Note:

Operate over the “Absolute Maximum Ratings” may cause permanent damage to the device. Exposure to such conditions for

extended time may still affect the reliability of the device.

Note 5: Operating the IC over this voltage is very easy to cause over voltage condition to VIN pin, SW pin, BS pin & EN pin.

Note 6: If the IC experienced OTP, then the temperature may need to drop to < 125 degree C to let the IC recover.
