♠ 40VIN, 75VOUT LED Controllers
Lub LT® 3755, LT3755-1 thiab LT3755-2 yog DC / DC controllers tsim los ua haujlwm raws li qhov chaw tsis tu ncua rau kev tsav tsheb siab tam sim no. Lawv tsav ib sab qis sab nraud N-channel fais fab MOSFET los ntawm kev tswj hwm sab hauv 7.15V khoom. Qhov ruaj khov zaus, tam sim no hom architecture ua rau kev ua haujlwm ruaj khov dhau ntau yam khoom siv thiab cov zis voltages. Lub hauv paus hais txog qhov hluav taws xob FB tus pin ua lub tswv yim rau ntau yam kev tiv thaiv LED,thiab tseem ua rau nws ua tau rau lub converter ua haujlwm raws li qhov chaw tsis tu ncua-voltage. Lub zaus kho tus pin tso cai rau tus neeg siv los ua qhov zaus ntawm 100kHz mus rau 1MHz los ua kom zoo dua qub, kev ua haujlwm lossis cov khoom siv sab nraud.
LT3755 / LT3755-1 / LT3755-2 kev nkag siab cov zis tam sim no ntawm sab siab ntawm txoj hlua LED. High sab tam sim no sensing yog qhov yooj yim tshaj plaws rau kev tsav tsheb LEDs, tso cai rau boost, puck hom lossis puck-boost hom configuration. PWM cov tswv yim muab LED dimming piv txog li 3000: 1, thiab CTRL cov tswv yim muab ntxiv muaj peev xwm ua kom dimming.
