Ukushintsha Izilawuli
Izilawuli ezishintshayo ziwuhlobo lwesekhethi engaguqula i-voltage kanye ne-input current ibe i-voltage kanye nomsinga ophumayo ofaneleka kakhulu ukunika amandla isistimu ekhiqiza amandla ayo.Lezi zinhlobo zamasekhethi zaziwa nangokuthi iziguquli futhi zilungele ukulawula amandla adluliswa phakathi kwalawa maphuzu amabili okuxhumana ukuze kugcinwe i-voltage ephumayo engaguquki engaphakathi ngokuphephile kwemikhawulo yesekethe.Basebenza ngokusebenza kahle kakhulu kokuguqulwa kuneabalawuli bomugqafuthi unikeze inzuzo yokuphathwa kwamandla okungcono futhi okungabizi kakhulu esikhathini eside, kanye neqiniso lokuthi ngokuvamile awadingi ama-capacitor angaphandle.
Izilawuli zokushintsha zisetshenziselwa ini?
Lezi zinhlobo zezilawuli zivame ukusetshenziselwa izinhlelo zokusebenza ezisebenza ngebhethri yeseli elilodwa noma amaseli amaningi kanye namadivayisi kagesi aphathwayo anamandla ebhethri njengamakhamera edijithali, amakhonsoli amageyimu aphathwayo, izilawuli nokuningi.Inzuzo eyinhloko yokusebenzisa lezi ziguquli ezishintshayo esikhundleni sezilawuli ezilandelanayo ukuthi zinikeza ukuvikelwa kwesekethe emfishane futhi ziqinisekisa ukuvikelwa kwe-voltage eningi kanye ne-under-voltage.Futhi zilungele ukuvikela amasistimu e-elekthronikhi emazingeni okushisa angaphezulu kanye nomonakalo wamanje.
Izinhlobo zokulawula ukushintsha
I-Step-Up noma i-Boost Regulators - Lezi izinhlobo eziyisisekelo kakhulu zesilawuli sokushintshwa futhi zisetshenziselwa ukukhulisa amandla kagesi.
· Iziguquli ze-Step-Down noma ze-Buck-Boost - Zehlisa noma zihlehlise i-voltage ephumayo ngokuphathelene ne-voltage yokufaka

Incazelo ye-LP87524J-Q1
I-LP87524B/J/P-Q1 yakhelwe ukuhlangabezana nezidingo zokuphathwa kwamandla zamaphrosesa akamuva namapulatifomu kuzinhlelo zokusebenza zamandla ezimoto ahlukahlukene.Idivayisi iqukethe ama-converter cores amane e-DC-DC, alungiselelwa njengokuphumayo kwesigaba esisodwa esingu-4.Idivayisi ilawulwa i-I2Isixhumi esibonakalayo se-serial esihambisanayo no-C nangokuvumela amasignali.
Ukusebenza okuzenzakalelayo kwe-PFM/PWM (imodi ye-AUTO) kukhulisa ukusebenza kahle ebangeni elibanzi lokuphumayo lamanje.I-LP87524B/J/P-Q1 isekela i-remote voltage sensing ukunxephezela ukwehla kwe-IR phakathi kokuphumayo kwesilawuli nendawo yokulayisha (POL) ngaleyo ndlela ithuthukise ukunemba kwe-voltage ephumayo.Ngaphezu kwalokho iwashi elishintshayo lingaphoqwa kumodi ye-PWM futhi liphinde livumelaniswe newashi langaphandle ukuze kuncishiswe iziphazamiso.
Idivayisi ye-LP87524B/J/P-Q1 isekela ukukalwa kwamanje komthwalo ngaphandle kokwengezwa kweziphikisayo zangaphandle zenzwa yamanje.Ngaphezu kwalokho, i-LP87524B/J/P-Q1 isekela ukuqala okuhlelekayo nokubambezeleka kokuvala kanye nokulandelana okuvunyelanisiwe ukuze kusebenze amasiginali.Ukulandelana kungafaka namasiginali we-GPIO ukulawula izilawuli zangaphandle, ukushintsha kokulayisha nokusetha kabusha iphrosesa.Ngesikhathi sokuqalisa nokushintsha kwe-voltage, idivayisi ilawula izinga lokukhipha amandla ukuze kuncishiswe ukushuthwa kwe-voltage ephumayo kanye ne-in-rush current.
