Notes:

4. Test condition for PowerDi-123: Device mounted on 25.4mm x 25.4mm FR-4 PCB (10mm x 10mm 1oz copper, minimum recommended pad layout on

top layer and thermal vias to bottom layer ground plane). For better thermal performance, larger copper pad for heatsink is needed.

5. When mounted on 50.8mm x 50.8mm GETEK PCB with 25.4mm x 25.4mm copper pads.

6. Test condition for SOD-123: Device mounted on FR-4 PCB with 50.8mm x 50.8mm 2oz copper, minimum recommended pad layout on top layer and

thermal vias to bottom layer with maximum area ground plane. For better thermal performance, larger copper pad for heatsink is needed.

Notes:

7. The LED operating current is determined by the AL5809 current option index XXX, AL5809-XXXS/P1-7.

8. The Maximum LED current is also limited by ambient temperature and power dissipation such that junction temperature should be kept less than or equal

to +125°C.

Notes:

9. All voltages unless otherwise stated are measured with respect to OUT pin.

10. Measure the percentage degree of LED current variation when VInOut varies from 2.5V to 60V for each current option.

11. Apply the power linearly to the chip until the device starts to turn on.
