Ukushintsha Isilawuli

Isilawuli esishintshayo siyisilawuli sikagesi esisebenzisa into eshintshayo ukuze siguqule amandla angenayo abe amandla kagesi ashaya ngamandla, ebese abushelelezi kusetshenziswa ama-capacitor, inductors, nezinye izakhi.
Amandla anikezwa kusukela kokokufakayo kuya kokuphumayo ngokuvula iswishi (MOSFET) kuze kufinyelelwe i-voltage oyifunayo.
Uma i-voltage ephumayo ifinyelela inani elinqunyelwe kusengaphambili isici sokushintsha IYAVALWA futhi awekho amandla okufaka asetshenzisiwe.
Ukuphinda lo msebenzi ngesivinini esikhulu kwenza kube nokwenzeka ukuhlinzeka i-voltage ngendlela efanele futhi ngokukhipha ukushisa okuncane.

Incazelo ye-TPS54560B-Q1

I-TPS54560B-Q1 iyi-60 V, 5 A, isilawuli sezinyathelo eziphansi esinohlangothi oluphezulu oluhlanganisiwe lwe-MOSFET.Idivayisi ikwazi ukusinda ekulahlekeni komthwalo kufika ku-65V nge-ISO 7637 ngayinye. Ukulawula imodi yamanje kunikeza isinxephezelo esilula sangaphandle nokukhetha kwengxenye eguquguqukayo.Imodi ye-ripple skip skip ephansi inciphisa ukunikezwa komthwalo wamanje ku-146 µA.Ukuvala ukunikezwa kwamandla kwehliselwa ku-2 µA uma iphinikhodi idonswa phansi.
I-Undervoltage lockout isethwe ngaphakathi kokuthi 4.3 V kodwa inganyuswa kusetshenziswa iphinikhodi yokunika amandla.Irempu yokuqalisa i-voltage ephumayo ilawulwa ngaphakathi ukuze inikeze ukuqalisa okulawulwayo nokuqeda ukushuba ngokweqile.
Ububanzi befrikhwensi yokushintsha okubanzi buvumela ukusebenza kahle noma usayizi wengxenye yangaphandle ukuthi uthuthukiswe.Okukhiphayo kukhawulelwe umjikelezo nomjikelezo.Ukugoqa imvamisa nokuvalwa kwe-thermal kuvikela izingxenye zangaphakathi nezangaphandle phakathi nesimo sokugcwala kakhulu.
I-TPS54560B-Q1 itholakala kuphakheji ye-HSOP PowerPAD™ eyi-8-terminal ethuthukisiwe ngokushisa.
