♠ TPS6282x 2.4-V ki te 5.5-V Whakauru, 1-, 2-, 3-, 4-A Kaitahuri-a-raro me te 1% Tika Putanga
Ko te TPS6282x he whanau kaitahuri DC-DC tukutahi ngawari ki te whakamahi me te iti rawa o te naianei o te 4 μA anake. I runga i te topology DCSControl, ka tukuna he urupare tere tere. Ko te tohutoro o roto ka taea te whakahaere i te ngaohiko whakaputa ki raro ki te 0.6 V me te tika o te ngaohiko urupare teitei o te 1% i runga i te awhe pāmahana hononga -40°C ki te 125°C. Ko nga taputapu whanau he titi-topin me te BOM-ki-BOM hototahi. Ko te otinga katoa e hiahiatia ana he inductor iti 470-nH, he 4.7-µF pūnga whakaurunga kotahi me te rua 10-µF ranei kotahi 22-µF pūnga putanga.
Kei te waatea te TPS6282x i roto i nga momo reka e rua. Ko te tuatahi ko te aratau penapena hiko kua uru aunoa ki te pupuri i te kaha ki raro ki nga kawenga tino mama mo te whakaroa i te wa o te pākahiko punaha. Ko te tuarua ka rere i roto i te kaha-PWM e pupuri ana i te aratau kawe haere tonu hei whakarite kia iti rawa te ripple i roto i te ngaohiko whakaputa me te auau whakawhiti kua rite. Kei roto i te taputapu he tohu Power Good me te ara iahiko whakaoho ngohengohe o roto. Ka taea ki te mahi i roto i te 100% aratau. Mo te parenga he, ka whakauruhia he whakamarumaru ara iahiko poto HICCUP tae atu ki te katinga wera. Kei te waatea te taputapu i roto i te kete 6-pin 1.5 x 1.5-mm QFN, e tuku ana i te otinga kiato mana teitei.
