Ko nga waahanga mo te TPS61088RHLR

whakaahuatanga poto:

Ko te TPS61088 he kaha teitei o te kaha, he tino whakakotahi i te kaitahuri whakanui tukutahi me te whakawhiti hiko 11-mΩ me te whakawhiti whakatika 13-mΩ, e whakarato ana i te tino pai, te otinga iti-rahi mo nga punaha kawe.Ko te TPS61088 he whanui ngaohiko whakaurunga o te 2.7V ki te 12V hei tautoko i nga tono e whakamahia ana e nga papahiko Li-ion kotahi-putau-rua ranei.Ko te taputapu he 10A te kaha whakawhiti o naianei ka taea te tuku ngaohiko whakaputa ki te 12.6V.

Whakaahuatanga

Ko te TPS61088 he kaha teitei, he tino whakakotahi i te kaitahuri whakanui tukutahi me te whakawhiti hiko 11-mΩ me te whakawhiti whakatika 13-mΩ ki te whakarato i te pai teitei me te otinga rahi iti i roto i nga punaha kawe.Ko te TPS61088 he awhe ngaohiko whakauru whanui mai i te 2.7 V ki te 12 V hei tautoko i nga tono me nga pākahiko Lithium kotahi-putau-rua ranei.Ko te taputapu he 10-A te kaha o naianei whakawhiti me te kaha ki te whakarato i te ngaohiko whakaputa ki runga ki te 12.6 V. Ka whakamahia e te TPS61088 te urutau o te wa-waahi teitei o naianei mana whakahaere o naianei hei whakarite i te ngaohiko whakaputa.I roto i te ahua taumaha ki te taumaha, ka mahi te TPS61088 i roto i te aratau huringa whanui puihi (PWM).I roto i te ahua o te kawenga mama, e rua nga momo mahi kua tohua e te pine MODE.

Ko tetahi ko te aratau whakarereketanga auau (PFM) hei whakapai ake i te kaha me tetahi atu ka peehia te aratau PWM ki te karo i nga raru tono na te iti o te huringa whakawhiti.Ko te auau whakawhiti i te aratau PWM ka taea te whakarite, mai i te 200 kHz ki te 2.2 MHz e te parenga o waho.Ka whakatinanahia e te TPS61088 he mahi ngawari-tīmata ka taea te whakarite me te mahi tepe o te tihi o naianei.I tua atu, ka whakaratohia e te taputapu te whakamarumaru o te ngaohiko putanga 13.2-V, te whakamarumaru o te huringa-a-huringa, me te whakamarumaru whakamarumaru wera.Kei te waatea te TPS61088 i roto i te kete 4.50-mm × 3.50-mm 20-pin VQFN.
