Whakaahuatanga o TPS630250
Ko te TPS63025x he tino pai, he iti nga kaitahuri peera-whakanui o naianei e tika ana mo te tono he teitei ake, he iti ake ranei te ngaohiko whakauru i te putanga.Ka taea e nga au putanga te eke ki te 2 A i roto i te aratau whakanui me te teitei ki te 4 A i te aratau peera.Ko te nuinga o naianei i roto i nga huringa he iti ki te uara angamaheni o 4 A. Ko te TPS63025x te whakahaere i te ngaohiko whakaputa i runga i te awhe ngaohiko whakauru katoa ma te huri aunoa i waenga i te peera, i te aratau whakanui ranei i runga i te ngaohiko whakauru e whakarite ana i te whakawhiti pai i waenga i nga tikanga.Ko te kaitahuri peera-boost e ahu mai ana i runga i te auau i whakaritea, te kaitahuri-whanui-whakawhitiwhiti (PWM) te kaiwhakahaere ma te whakamahi i te whakatika tukutahi kia whiwhi ai i te tino pai.I nga au o te uta iti, ka uru te kaitahuri ki te Aratau Tiaki Hiko hei pupuri i te tino pai ki runga i te awhe o naianei kawenga.He pine PFM / PWM ka taea e te kaiwhakamahi te whiriwhiri i waenga i te mahi aratau PFM / PWM aunoa me te mahi PWM kaha.I roto i te aratau PWM ka whakamahia te auau-auau o te tikanga 2.5 MHz.Ko te ngaohiko whakaputa ka taea te whakamaarama ma te whakamahi i te kaiwehewehe parenga o waho, ka whakatauhia ranei a roto ki te maramara.Ka taea te whakakore i te kaitahuri hei whakaiti i te rere o te pākahiko.I te wa e kati ana, ka momotuhia te kawenga mai i te pākahiko.Ko te taputapu kei roto i te kete 20-titi WCSP te ine 1.766 mm × 2.086mm me te 14-pin HotRod mokihi te ine 2.5 mm × 3mm.
