♠ TPS54622 4.5-V kuya ku-17-V Okokufaka, 6-A Ukuguquguquka Kwesinyathelo-Phansi kwe-SWIFT™ Okuvumelanisiwe Ngokuvikelwa kwe-Hiccup
Idivayisi ye-TPS54622 kuphakheji ye-VQFN ethuthukiswe ngokushisa engu-3.5-mm × 3.5-mm iyi-converter enesici esigcwele engu-17-V, 6-A ehambisanayo eyehlayo eyenzelwe imiklamo emincane ngokusebenzisa ukusebenza kahle okuphezulu nokuhlanganisa ama-MOSFET aseceleni okuphezulu naphansi. Ukonga okwengeziwe kwesikhala kufinyelelwa ngokulawulwa kwemodi yamanje, okunciphisa ukubalwa kwengxenye, futhi ngokukhetha imvamisa yokushintsha ephezulu, kunciphisa umkhondo we-inductor.
Irempu yokuqala kagesi okukhiphayo ilawulwa iphinikhodi ye-SS/TR, evumela ukusebenza njengokuphakelwa kwamandla okuzimele noma ezimweni zokulandelela. 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. Ukuvikelwa kwe-Hiccup kuqalwa uma isimo se-overcurrent saqhubeka isikhathi eside kunesikhathi esisethiwe. Ukuvikelwa kwe-thermal hiccup kukhubaza idivayisi lapho izinga lokushisa lokufa lidlula izinga lokushisa elishisayo lokuvala shaqa futhi linike amandla ingxenye futhi ngemva kwesikhathi sokuvala ukuvala kwe-thermal esakhelwe ngaphakathi.
