Incazelo
I-TPS54320 iyisiguquli esinesici esigcwele esingu-17-V, esingu-3-Asynchronous esiya phansi esilungiselelwa imiklamo emincane ngokusebenzisa ukusebenza kahle okuphezulu kanye nama-MOSFET ahlanganisiwe aseceleni okuphezulu naphansi.Ukonga okwengeziwe kwesikhala kufinyelelwa ngokulawulwa kwemodi yamanje, okunciphisa ukubalwa kwezingxenye, futhi
ukukhetha imvamisa yokushintsha ephezulu, kunciphisa unyawo lwe-inductor.Irempu yokuqalisa i-voltage ephumayo ilawulwa iphinikhodi ye-SS/TR evumela ukusebenza njengokuphakelwa kwamandla okuzimele noma ezimweni zokulandelela.Ukulandelana kwamandla nakho kuyenzeka ngokumisa ngendlela efanele ukunika amandla kanye nezikhonkwane ezinhle zokudonsa amandla.Umkhawulo wamanje wokujikeleza ngomjikelezo ku-FET yohlangothi oluphezulu uvikela idivayisi ezimweni ezigcwele kakhulu futhi uthuthukiswa umkhawulo wamanje wokuthola indawo ophansi ovimbela ukubaleka kwamanje.Ukuvikelwa kwe-Hiccup kuqalwa uma isimo se-overcurrent saqhubeka isikhathi eside kunesikhathi esisethiwe.Ukuvalwa kwe-thermal kukhubaza ingxenye lapho izinga lokushisa lokufa lidlula izinga lokushisa elishisayo lokuvala shaqa.I-TPS54320 itholakala nge-14-pin, 3.5-mm × 3.5-mm VQFN,iphakheji ethuthukisiwe ngokushisa.Ukwaziswa Kwedivayisi INGXENYE INOMBOLO YEPACKAGE BODY SIZE (NOM) TPS54320 VQFN (14) 3.50 mm × 3.50 mm Ukuze uthole wonke amaphakheji atholakalayo. isengezo esihlelekayo ekupheleni kweshidi ledatha.
