le output current up to 1.5A for MSOP-8E P package. Depending upon supply voltag e and external components, this convert er can provide up to 40W of output powe r. The AL8861Q integrates the power swi tch and a high-side output current sens ing circuit, which uses an external res istor to set the nominal average output current. Dimming can be realized by ap plying an external control s
