♠ 40VIN, 75VOUT Owongolera a LED
LT®3755, LT3755-1 ndi LT3755-2 ndi olamulira a DC/DC opangidwa kuti azigwira ntchito ngati gwero lanthawi zonse loyendetsa ma LED apamwamba kwambiri. Amayendetsa mbali yotsika yakunja ya N-channel mphamvu MOSFET kuchokera kumayendedwe amkati a 7.15V. Mafupipafupi okhazikika, mapangidwe amakono amakono amapangitsa kuti pakhale ntchito yokhazikika pamagulu osiyanasiyana operekera ndi kutulutsa magetsi. Pini ya FB yotchulidwa pansi imagwira ntchito ngati chothandizira pazinthu zingapo zachitetezo cha LED,komanso zimapangitsa kuti chosinthiracho chizigwira ntchito ngati gwero lamagetsi okhazikika. Pini yosinthira pafupipafupi imalola wogwiritsa kukonza ma frequency kuchokera ku 100kHz mpaka 1MHz kuti akwaniritse bwino, magwiridwe antchito kapena kukula kwa gawo lakunja.
The LT3755/LT3755-1/LT3755-2 mphamvu yotuluka pakali pano patali pa chingwe cha LED. Kuzindikira kwapambali komweko ndiye njira yosinthika kwambiri yoyendetsera ma LED, kulola kukwera, mayendedwe a buck kapena kasinthidwe ka buck-boost mode. Kulowetsa kwa PWM kumapereka ma dimming ratios a LED mpaka 3000:1, ndipo kulowetsa kwa CTRL kumapereka kuthekera kowonjezera kwa analogi.
