Incazelo Yengqalasizinda Yezokuxhumana I-TPS54620 ku-3.50 mm ethuthukisiwe ×
Iphakethe le-QFN elingu-3.50 mm ligcwele ngokugcwele i-17-V, 6-A, i-synchronous, i-converter eya phansi ethuthukiselwa imiklamo emincane ngokusebenzisa ukusebenza kahle okuphezulu nokuhlanganisa ama-MOSFET aseceleni okuphezulu naphansi. isilawuli semodi, esinciphisa ukubalwa kwengxenye, nangokukhetha imvamisa yokushintsha okuphezulu, ukunciphisa umkhondo we-inductor.Irempu yokuqalisa i-voltage ephumayo ilawulwa iphinikhodi ye-SS/TR evumela ukusebenza njengokuphakelwa kwamandla okuzimele noma ekulandeleni. izimo.Ukulandelana kwamandla nakho kuyenzeka ngokumisa kahle ukunika amandla kanye nezikhonkwane ezinhle zokudonsa amandla.Umkhawulo wamanje we-Cycle-by-cycle ku-FET yohlangothi oluphezulu uvikela idivayisi ezimweni ezigcwele kakhulu futhi uthuthukiswa umkhawulo wamanje wokuthola indawo ophansi ovimbela ukubaleka kwamanje.Kukhona nomkhawulo wamanje ocwilayo oseceleni ophansi ovala i-MOSFET eseceleni eliphansi ukuze kunqandwe ukuhlehla kwamanje okweqile.Ukuvalwa kwe-thermal kukhubaza ingxenye lapho izinga lokushisa lokufa lidlula izinga lokushisa elishisayo lokuvala shaqa.
