♠ LP8866S-Q1 Whakaaturanga Aunoa Atekōkiri rama-whakamuri me te ono nga hongere 150-mA

Ko te LP8866S-Q1 he taraiwa LED tino kaha me te kaiwhakahaere whakatairanga.Ko nga totohu o naianei e ono e tautoko ana i te nekehanga o te wahanga ka whakatika aunoa i runga i te maha o nga hongere e whakamahia ana.Ka taea te whakahaere i te kanapa o te ao ma te atanga I²C, te whakauru PWM ranei.

Ko te kaiwhakahaere whakatairanga he mana ngaohiko whakaputa urutau i runga i nga ngaohiko o te upoko o nga totohu o naianei LED.Ko tenei ahuatanga ka whakaiti i te whakapau hiko ma te whakatika i te ngaohiko whakanui ki te taumata iti rawa i roto i nga ahuatanga katoa.Ka taea e te LP8866S-Q1 te aukati i te whakararuraru mo te roopu reo irirangi AM.

Ko te LP8866S-Q1 e tautoko ana i te hanga-i roto i te ranu PWM dimming me te tairitenga o naianei dimming, e whakaiti ana i te EMI, e whakaroa ana i te roanga o te LED, me te whakanui ake i te katoa o te mahi mata.
