♠ 40VIN, 75VOUT LED Igenzura
LT®3755, LT3755-1 na LT3755-2 ni abagenzuzi ba DC / DC bagenewe gukora nkisoko ihoraho-yo gutwara LED ndende. Batwara uruhande rwo hasi rwo hanze N-umuyoboro MOSFET uhereye imbere imbere 7.15V itanga. Inshuro ihamye, uburyo bwububiko bwubaka bivamo imikorere ihamye kumurongo mugari wo gutanga no gusohora voltage. Ubutaka buvugwa na voltage FB pin ikora nkibintu byinshi birinda LED,kandi binatuma bishoboka ko uhindura akora nkisoko ya voltage ihoraho. Imirongo ihindura pin yemerera uyikoresha porogaramu kuva kuri 100kHz kugeza 1MHz kugirango yongere imikorere, imikorere cyangwa ubunini bwibigize hanze.
LT3755 / LT3755-1 / LT3755-2 ibyiyumvo bisohoka bigezweho kuruhande rwo hejuru rwumugozi wa LED. Kuruhande rwo hejuru rwunvikana nuburyo bworoshye bwo gutwara LED, kwemerera kuzamura, uburyo bwamafaranga cyangwa uburyo bwo kuzamura buck. PWM yinjiza itanga ibipimo bya LED bigera kuri 3000: 1, naho CTRL yinjiza itanga ubundi bushobozi bwo kugereranya.
