Haohiko Whakakotahi Taketake Hou TPS63070RNMR

Te Taiwhanga Whakakotahi Taketake Hou TPS63070RNMR Whakaahua Whakaatu

whakaahuatanga poto:

Ko te TPS6307x he kaitahuri teitei, he iti te noho humarie o naianei kaitahuri peera e tika ana mo nga tono ka nui ake, ka iti ake ranei te ngaohiko whakauru i te ngaohiko whakaputa.Ka taea e nga au putanga te eke ki te 2 A i roto i te aratau whakanui me te aratau peera.Ko te kaitahuri peera-boost e hangai ana i runga i te auau kua whakaritea, te kaitahuri-whanui-nui (PWM) te kaiwhakahaere ma te whakamahi i te whakatikatika tukutahi kia pai ai te kaha.I nga ohanga iti o te uta, ka uru te kaitahuri ki te Aratau Tiaki Hiko kia mau tonu te kaha ki runga i te whānuitanga o te awhe o naianei.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.Kei te waatea te taputapu i roto i te kete 2.5 mm x 3 mm QFN.

Kupu Whakataki

Ko te kaitahuri huri (DC-DC converter) he kai whakahaere (whakapumau te mana hiko).Ka taea e te kaiwhakahaere whakawhiti te huri i te ngaohiko o naianei (DC) whakauru ki te ngaohiko o naianei tika (DC) e hiahiatia ana.
I roto i tetahi taputapu hiko, i etahi atu taputapu ranei, ko te kaiwhakahaere whakawhiti te mahi ki te huri i te ngaohiko mai i te pākahiko, i tetahi atu puna hiko ranei ki nga ngaohiko e hiahiatia ana e nga punaha o muri mai.

Ka rite ki te whakaahua i raro nei e whakaatu ana, ka taea e te kaiwhakahaere whakawhiti te hanga i te ngaohiko whakaputa (V_{KI WAHO}) he teitei ake (te pikinga, te whakanui), kei raro iho (te hikoi ki raro, te peera) he rereke rereke ranei i tera o te ngaohiko whakauru (V_IN)
Te huri i nga ahuatanga whakahaere

Ko nga korero e whai ake nei he whakamaarama mo nga ahuatanga o te kaiwhakahaere whakawhiti kore-motuhake.

Te kaha teitei

Ma te whakahuri i te huānga whakakā me te OFF, ka taea e te kaiwhakahaere whakawhiti te huri i te hiko tino kaha i te mea ka tukuna e ia te nui o te hiko ina hiahiatia anake.
Ko te kaiwhakahaere raina tetahi atu momo kaiwhakahaere (te tuku hiko whakapumau), engari na te mea ka whakakorehia e ia nga toenga hei wera i roto i te huringa huringa ngaohiko i waenga i te VIN me te VOUT, kaore i te tino rite ki te kaiwhakatika whakawhiti.
Ko te kaiwhakahaere raina tetahi atu momo kaiwhakahaere (te tuku hiko whakapumau), engari na te mea ka whakakorehia e ia nga toenga hei wera i roto i te huringa huringa ngaohiko i waenga i te VIN me te VOUT, kaore i te tino rite ki te kaiwhakatika whakawhiti.

Haruru

Ko te huānga whakakā ON/OFF i roto i te kaiwhakahaere whakahuri ka puta he huringa ohorere i roto i te ngaohiko me te naianei, me nga waahanga pirinoa e whakaputa tangi ana, ka puta katoa te haruru ki te ngaohiko whakaputa.
Ko te whakamahi i te whakatakotoranga papa e tika ana hei whakaiti i te ngangau.Hei tauira, te arotau i te whakatakotoranga o te puritanga me te inductor me te waea waea/ranei.Mo etahi atu korero mo te hanga o te haruru (tangi) me pehea te whakahaere, tirohia te Panui Taupānga "Nga Whakataunga Haruru Whakawhiti Whakawhiti Raro."
