Whakaahuatanga
Ko te whanau o nga taputapu TPS9260x-Q1 he hongere kotahi me te ara-rua-nui-taha-naianei LED
taraiwa.Ma te tino whakamarumaru me nga tātaritanga, kua whakatapua tenei whanau o nga taputapu mo nga rama rama o mua.Ko te turanga o ia taraiwa motuhake ko te tihi-naianei-aratau whakanui mana.E rua nga kowhiti urupare motuhake o ia kaiwhakahaere, he kowiri urupare-a-waa me te taha teitei-te-te-te-te-rangi me te ngaohiko-urupare me te whatunga whakawehe-whakawehe-a-waho.Ka tukuna e te kaiwhakahaere he ngaohiko putanga tonu, he naianei whakaputa tonu ranei.Ko te kawenga hono ka whakatau mena ka whakatauhia e te taputapu te iahiko putanga tonu (mehemea ka tae te ara iahiko ki te taunga o naianei i mua atu i te ngaohiko huinga-tohu) he ngaohiko whakaputa tonu ranei (mehemea ka tae te ara iahiko ki te taurangi ngaohiko ka tae tuatahi, hei tauira, i te waahi tuwhera. -Te ahua o te utaina).Ka tautokohia e ia kaiwhakahaere nga ahuatanga angamaheni katoa penei i te whakanui, te whakanui-ki-pakihiko, te SEPIC, te flyback ranei. Ko nga whakamahinga o te taraiwa PMOS FET taha-tiketike mo te whakaiti PWM o te aho LED me te tapahi i te mea he poto o waho. ara iahiko ki te GND hei whakamarumaru i te ara iahiko.Mohiohio Pūrere(1)WAHAHANGA NUI SENSE-VOLTAGE
