Kaituku Whakawhiti

Ko te kaitakawaenga whakawhiti he kaiwhakatika ngaohiko e whakamahi ana i te huānga whakawhiti ki te huri i te tuku hiko taumai ki te ngaohiko pupuhi, katahi ka whakaenehia ma te whakamahi i nga puri, inductors, me etahi atu huānga.
Ka tukuna te hiko mai i te whakauru ki te whakaputanga ma te huri i te whakaka (MOSFET) kia tae ra ano te ngaohiko e hiahiatia ana.
Kia tae te ngaohiko whakaputa ki te uara kua whakaritea ka whakawetohia te huānga whakakā ka kore e pau te mana whakauru.
Ko te tukurua i tenei mahi i nga tere tere ka taea te tuku ngaohiko pai me te iti ake o te whakaputanga wera.

Whakaahuatanga mo te TPS54560B-Q1

Ko te TPS54560B-Q1 he 60 V, 5 A, he kaiwhakahaere whakaheke me te MOSFET taha teitei.Ka ora tonu te taputapu ki te 65V mo ia ISO 7637. Ko te whakahaere aratau o naianei he utu ngawari o waho me te kowhiringa waahanga ngawari.Ma te iti o te ripple pulse mokowhiti ka whakaiti i te naianei kore utaina ki te 146 µA.Ka whakaitihia te naianei whakaweto ki te 2 µA ka toia te titi whakaahei.
Ko te kati ngaohiko i roto i te 4.3 V engari ka taea te whakanui ma te whakamahi i te titi whakaahei.Ko te reanga whakaoho ngaohiko whakaputa ka whakahaeretia a roto ki te whakarato i te tiimata me te whakakore i te pupuhi.
Ma te awhe whanui whakawhiti ka taea te pai, te rahi o te waahanga o waho ranei ki te whakatika.He iti te naianei putanga i ia huringa.Ko te kopikopiko me te katinga waiariki hei tiaki i nga waahanga o roto me waho i te wa e taumaha ana te taumaha.
Kei te waatea te TPS54560B-Q1 i roto i te kete HSOP PowerPAD™ 8-waahanga kua whakareia ake.
