BD18336NUF-M shine 3 x 3 x 1mm direban IC na yanzu wanda zai iya sadar da 400mA a gaba (600mA a 50% zagayowar aiki) zuwa cikin igiyar farin LED guda uku ko igiyoyin layi ɗaya na LEDs.
"An dakatar da zafi daga LEDs ta hanyar hada-hadar aiki ta yanzu," a cewar Rohm. "Yanayin daidaitaccen yanayin wutar lantarki yana iyakance zafin da LED ke samarwa, yana kara rayuwarsu, wanda ya sa direban LED ya dace da farare da kuma LEDs ja da rawaya."
Har ila yau, bayanin yanayin zafi don kara aminci, kariyar sun hada da bude bude LED, fitowar gajeren kewaya na kariya, SET fil gajeren kewaya na kariya (duba zane), mara karfin wutan lantarki, wucewar yanzu a rage karfin wuta, fitowar tutar kuskure. Ba duk kariya ke aiki tare da zaren igiyar LED ba.
Sakamakon fitarwa na yau da kullun-ana iya shirya shi, kuma akwai ginanniyar PWM oscillator wanda ke aiki tare da RC na waje don daidaita igiyar, ko za a iya amfani da siginar PWM na waje.
