AP62600 Kaihuri Buck Converter

Ko te kaitahuri kopere kopere Diode he whakatutuki i te whakautu tere, tere te whakaurutanga o te putunga, me te riipene hiko iti

Diodes AP62600 Synchronous Buck Converter AP62600 he Diode he 6 He kaitahuri peere orite me te awangawanga whakauru whanui o te 4.5 V ki te 18 V. Ka whakauruhia e te taputapu he MOSFET kaha-nui 36 mΩ me te MOSFET mana iti 14 mΩ ki te whakarato i te mahi tika -Whakaari o te whakawhitinga DC / DC. Ko te taputapu AP62600 e whakamahia ana ma te whakaiti i te tatau a-waho mo te whakamahi i te mana whakahaere i runga i te waa (COT) ki te whakatutuki i te urupare tere, tere te whakatikatika tere, me te riipene hiko iti. Ko te hoahoa AP62600 e arotau ana mo te whakahekenga whakawehe hiko (EMI). He kaupapa a te taraiwa a te taraiwa a te taputapu ki te kore e huri i te tangi o te kowhatu kaore he patunga MOSFET me te whakaweto, ka whakaiti i te haruru EMI whakaohooho nui na te MOSFET whakawhiti. E waatea ana te taputapu kei roto i te kete V-QFN2030-12 (Momo A).
