LP8866S-Q1 Direban Mota na LED-Baya Direba tare da Tashoshi 150-mA Shida
LP8866S-Q1 direban LED ne mai inganci mai ƙarfi tare da mai sarrafa haɓakawa. Madaidaicin madaidaicin madaidaicin shida na yanzu yana goyan bayan canjin lokaci wanda aka daidaita ta atomatik dangane da adadin tashoshi da ake amfani da su. Ana iya sarrafa hasken LED a duk duniya ta hanyar haɗin I²C ko shigarwar PWM.
Mai kula da haɓaka yana da ikon sarrafa wutar lantarki mai daidaitawa dangane da ƙarfin wutar lantarki na LED na nutsewar yanzu. Wannan fasalin yana rage yawan amfani da wutar lantarki ta hanyar daidaita ƙarfin ƙarfin haɓaka zuwa mafi ƙarancin isasshen matakin a kowane yanayi. Mitar daidaitacce mai faɗin ke ba da damar LP8866S-Q1 don guje wa tashin hankali ga rukunin rediyon AM.
LP8866S-Q1 yana goyan bayan ginanniyar haɓakar PWM dimming da dimming analog na yanzu, wanda ke rage EMI, yana tsawaita rayuwar LED, kuma yana ƙara yawan ingancin gani.
