♠ 40VIN, 75VOUT Kaiwhakahaere arahina
Ko te LT®3755, LT3755-1 me LT3755-2 he kaiwhakahaere DC/DC i hangaia hei mahi hei puna o naianei tonu mo te taraiwa i nga rama teitei o naianei. Ka peia e ratou he MOSFET hiko hiko-N-waho taha iti mai i te tukunga 7.15V a-roto. Ko te auau tonu, te hoahoanga aratau o naianei ka hua te mahi i runga i te whanuitanga o te tuku me nga ngaohiko whakaputa. He titi FB ngaohiko tohu whenua hei whakaurunga mo etahi ahuatanga whakamarumaru LED,a ka taea hoki e te kaitahuri te mahi hei puna ngaohiko-mau. Ma te pine whakatikatika auau ka taea e te kaiwhakamahi te whakarite i te auau mai i te 100kHz ki te 1MHz ki te arotau i te pai, te mahi, te rahi o te waahanga o waho ranei.
Ko te LT3755/LT3755-1/LT3755-2 te ahua o naianei kei te taha teitei o te aho LED. Ko te taha teitei o naianei te kaupapa ngawari mo te taraiwa LED, ka taea te whakanui, te aratau peera, te whirihoranga aratau peera ranei. Ko te whakaurunga PWM e whakarato ana i nga owehenga whakamarumaru LED ki te 3000:1, a ko te whakauru CTRL e whakarato ana i te kaha taapiri tairitenga.
