Note: 4.

Stresses greater than 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 under “Recommended

Operating Conditions” are not implied. Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability.

5. For better performance, the AL3066 should have high voltage pins CS and OVP. If CS or OVP pin is added to 16V, the IC will not smoke

or burn.

6. Device mounted on 2"x2" FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.
