Note:

5. When mounted on 50.8mm x 50.8mm GETEK PCB with 25.4mm x 25.4mm 2oz copper pads. For better thermal performance, larger copper pad for

heat-sink is needed.

6. Stresses greater than the Absolute Maximum Ratings specified above may cause permanent damage to the device. These are stress

ratings only, and 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.

Note:

7. DC power supply slew rate set at 10V/msec to avoid any excessive inrush current.

8. Apply the power supply voltage linearly to the chip until the device starts to turn on (output LED current reaches 5% of the desired current options).

The minimum power up voltage may vary with different current options.

9. Based on ATE trimmed accuracy at +25°C.

10. This parameter only guaranteed by design, not tested in production.
