Applications Information
The LED current is determined by the total resistance between the V
in the PCB and BOM).
C4 decouples the LED connections, again to minimize EMI, as well as smoothing the current.
D1 operates as the freewheeling diode, providing a current path for the LED current when the power switch at SW pin is off.
AL8806EV3 BOM
The AL8806 guarantees high level of performance both with 12V
