♠ TPS92638-Q1 8-Channel Linear Direba Direba Tare da Dimming PWM
TPS92638-Q1 direban LED madaidaiciyar tashoshi takwas ne tare da sarrafa dimming PWM. Tsarinsa shine manufa don tuki igiyoyi masu yawa na LED har zuwa matsakaici
ikon iyaka.
Wannan na'urar na iya fitar da igiyoyi har zuwa takwas tare da LED guda ɗaya zuwa uku a cikin kowane igiya, a jimlar halin yanzu har zuwa 70mA a kowane tashoshi. Abubuwan da aka fitar na iya kasancewa a layi daya don samar da tuƙi mafi girma na yanzu har zuwa 560mA.
A cikin aikace-aikacen kirtani da yawa, na'urar tana ba da fa'idar samun haɗin haɗin-cathode gama-gari na ƙwanƙwasa LED. Don haka, ana buƙatar waya guda ɗaya kawai da ake buƙata maimakon ɗaya ta kowane kirtani na LED wanda tsarin da ke da ƙananan ma'anar halin yanzu zai buƙaci.
Na'urar tana da damar canza hasken LED tsakanin babban na yanzu da ƙananan na yanzu don aikace-aikacen tsayawa da wutsiya. Resistors guda biyu sun saita matakan LED guda biyu na yanzu daga kowane fitarwa.
Na'urar lura da zafin jiki da aka haɗa tana rage firikwensin LED na yanzu idan yanayin mahaɗin IC ya wuce ma'aunin zafi. Ana iya tsara ma'aunin zafin jiki ta hanyar resistor na waje. Mutum na iya kashe fasalin yanayin duba yanayin zafi ta hanyar haɗa fil ɗin TEMP zuwa ƙasa. Fitar da zafin mahaɗar azaman wutar lantarki ana samunsa azaman zaɓin shirin masana'anta.
