Notes:
4. For 100% brightness either leave floating or connect to 1.25V relative to GND.
5. AP8801 will operate at higher frequencies but accuracy will be affected due to propagation delays.
6. For most applications the LED current will be within 8% over the duty cycle range specified. Duty cycle accuracy is also dependent on
propagation delay. Smaller size inductors can be used but LED current accuracy may be greater than 8% at extremes of duty cycle. This is most
noticeable at low duty cycles (less than 0.1) or when the input voltage is high and only one LED is being driven.

Notes:
7. Refer to figure 6 for the device derating curve.
8. Test condition for SO-8 and MSOP-8: Device mounted on FR-4 PCB, 2”x2”, 2oz copper, minimum recommended pad layout on top layer and
thermal vias to bottom layer ground plane. For better thermal performance, larger copper pad for heat-sink is needed.
