Note

(1) The specification values indicated “AC” is VSWH to PGND, -8 V (< 20 ns, 10 μJ), min. and 30 V (< 50 ns), max.

(2) The specification value indicates “AC voltage” is VBOOT to PGND, 36 V (< 50 ns) max.

(3) The specification value indicates “AC voltage” is VBOOT to VPHASE, 8 V (< 20 ns) max.

(4) Output current rated with testing evaluation board at TA = 25 °C with natural convection cooling. The rating is limited by the peak evaluation

board temperature, TJ = 150 °C, and varies depending on the operating conditions and PCB layout. This rating may be changed with different

application settings.

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.
