Caution:

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;

functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be

affected by exposure to absolute maximum rating conditions for extended periods of time.

Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling

and transporting these devices.

Notes:

4. AL8807A analog dimming range extends below 10% but at reduced LED current accuracies and may not turn completely off. Switching frequencies will

also be increased.

5. Maximum switch current is dependent on power dissipation and junction temperature.
