Izingxenye ze-Electronic LM5165YDRCR Izingxenye ze-IC I-Chip Ehlanganisiwe Esitoko
I-MOSFET yesiteshi esiphezulu ingasebenza ngo-100% womjikelezo womsebenzi ku-voltage ephansi yokuyeka futhi ayidingi i-bootstrap capacitor yesango lokushayela.Futhi, indawo yokusetha umkhawulo yamanje iyalungiseka ukuze kuthuthukiswe ukukhetha kwe-inductor kwemfuneko ethile yamanje yokuphumayo.Izinketho zesikhathi zokuqalisa ezikhethekayo nezilungisekayo zihlanganisa ukubambezeleka okuncane (akukho siqalo esithambile), okulungisiwe ngaphakathi (900 µs), kanye nesiqalo esithambile esihlelekayo kusetshenziswa i-capacitor.Inkomba ye-PGOOD evulekile ingasetshenziselwa ukulandelana, ukubika amaphutha, nokuqapha amandla kagesi okukhiphayo.I-LM5165 buck converter iyatholakala ku-10-pin, 3-mm × 3-mm, iphakheji ye-VSON-10 ethuthukisiwe ngokushisa no-0.5-mm pin pitch.

Ukushintsha Izilawuli
1.Kuyini Ukushintsha Izilawuli:
I-voltage regulator iyithuluzi elenza i-voltage ephumayo izinze futhi iqukethe isekethe yesilawuli se-voltage, isifunda sokulawula, kanye ne-servo motor.Lapho i-voltage yokufaka noma umthwalo ushintsha, isilawuli silawula amasampula esekethe, siqhathanise futhi sikhulise, bese sishayela i-servo motor ukuze sizungeze ukuze kushintshe indawo yebhulashi lekhabhoni yomlawuli.Igcina i-voltage ephumayo izinzile ngokulungisa ngokuzenzakalelayo isilinganiso sokuphenduka kwekhoyili.
I-switching regulator isetshenziselwa ukukhiqiza amandla kagesi okukhiphayo ngokulawula i-transistor ukuthi ishintshe phakathi kwesimo se-ON, ne-OFF kanye nezingxenye zokugcina amandla (ama-capacitor nama-inductors) ukugcina i-voltage iqinile.Ilungiswa ngokulungisa isikhathi sokushintsha ngokuya ngamasampula empendulo we-voltage ephumayo.
Isingeniso somsebenzi
Isilawuli sikagesi siwuhlobo lwesekhethi yokuphakela amandla noma okokusebenza okuphakela amandla okungalungisa ngokuzenzakalelayo i-voltage ephumayo.Indima yesilawuli sikagesi ukuguquguquka hhayi ukufika ezidingweni zezinto zikagesi zokuzinzisa amandla kagesi ebangeni lawo lenani elimisiwe ukuze izinhlobonhlobo zamasekhethi noma izinto zokusebenza zikagesi zisebenze ngokujwayelekile ku-voltage elinganiselwe yokusebenza.
Ububanzi besicelo
I-voltage regulator ingasetshenziswa kabanzi emabhizinisini ezimboni nasezimayini, izizinda zikawoyela, izitimela, izindawo zokwakha, izikole, izibhedlela, ucwaningo lwesayensi, nezinye izindawo ezidinga ukuqina kwamandla kagesi.Futhi iguqulelwe kumakhompyutha kagesi, amathuluzi omshini wokunemba, i-computer tomography (CT), amathuluzi anembayo, izisetshenziswa zokuhlola, izibani zokuphakamisa, okokusebenza kwamanye amazwe, imigqa yokukhiqiza, nezinye izinto zokusebenza.Ngaphezu kwalokho, isilawuli sikagesi siphinde silungele i-voltage yokuphakelwa kwamandla aphansi noma aphezulu, ukushintshashintsha ekupheleni kwenethiwekhi yokusabalalisa i-low-voltage yabasebenzisi, kanye nezinguquko zomthwalo emishinini yamandla.I-voltage regulator ifaneleka ngokukhethekile kuzo zonke izidingo eziphakeme zokuqiniswa kwe-grid waveform voltage yezindawo zamandla.Izilawuli zamandla ezinxephezela amandla aphezulu zingaxhunywa kumajeneretha ashisayo, asebenza ngogesi, kanye namancane.
Ukwahlukanisa
Ngokohlobo oluhlukile lokuphumayo kwesilawuli, isilawuli ngokuvamile sihlukaniswa sibe isilawuli se-AC (ugesi wokusimamisa amandla kagesi we-AC) kanye nesilawuli se-DC (ugesi wokusimamisa amandla kagesi we-DC) izigaba ezimbili.
Isilawuli sikagesi se-AC: isilawuli sikagesi sinamashumi amakhulu kuya ezinkulungwaneni zama-kilowatts esilawuli sikagesi se-AC, siwukunikezwa kwamandla amakhulu okuhlola kanye nezimboni, amandla okusebenza kwemishini yezokwelapha.Kukhona futhi izilawuli ezincane ze-AC voltage zama-watts ambalwa ukuya kuma-kilowatts ambalwa, okungamalabhorethri amancane noma izinto zasendlini ukuze zinikeze amandla ekhwalithi ephezulu.
Izilawuli ze-DC: Ngokwesimo sokusebenza se-tube yokulungisa, abalawuli be-DC bavame ukuhlukaniswa ngezigaba ezimbili: izilawuli ze-ware ne-switching.Isilungisi sokushintsha isilawuli, isiyingi esibushelelezi sinohlobo lokufakwayo kwe-capacitor kanye nezinhlobo ezimbili zokuminyanisa ikhoyili, zidinga ukuguquguquka ngokuya ngendlela yesekethe yesilawuli sokushintshwa okufanele isetshenziswe.Uhlobo lokufakwayo lwekhoyili yokuminyanisa lusetshenziswa kuzilawuli zokushintshela eziya phansi, kuyilapho uhlobo lokufakwayo kwe-capacitor lusetshenziswa kuzilawuli zokushintsha ezikhuphukayo.
Lo mkhiqizo uyisiguquli sokuya phansi.
