LM5165YDRCR izixhobo zoMbane ze-IC ezidityanisiweyo kwi-stock

inkcazelo emfutshane:

Isixhobo se-LM5165 sicwecwe, kulula ukusisebenzisa, i-3-V ukuya kwi-65-V, i-ultra-low IQ ye-synchronous buck converter kunye nokusebenza okuphezulu kwi-voltage yegalelo elibanzi kunye nokulayisha uluhlu lwangoku.Ngamandla ahlangeneyo aphezulu kunye necala eliphantsi le-MOSFETs, ukuya kuthi ga kwi-150-mA yemveliso yangoku inokuhanjiswa kwii-voltages ezisisigxina ze-3.3 V okanye i-5 V okanye kwimveliso ehlengahlengiswayo.Umguquli wenzelwe ukwenza lula ukuphunyezwa ngelixa unikezela iinketho zokwandisa ukusebenza kwesicelo esijoliswe kuyo.Imowudi ye-Pulse Frequency Modulation (PFM) ikhethelwe ukusebenza kakuhle komthwalo wokukhanya okanye ukulawulwa rhoqo ngeXesha (COT) phantse rhoqo ukusebenza rhoqo.Zombini iinkqubo zokulawula azifuni imbuyekezo ye-loop ngelixa zibonelela ngomgca ogqwesileyo kunye nomthwalo wokuphendula okwethutyana kunye ne-PWM emfutshane ngexesha lemilinganiselo enkulu yokuguqulwa kwe-step-down.


Iinkcukacha zeMveliso

Iithegi zeMveliso

I-MOSFET yecala eliphezulu le-P-channel inokusebenza kumjikelo we-100% wombane ophantsi wokuyeka umbane kwaye ayifuni i-bootstrap capacitor kwi-gate drive.Kwakhona, indawo yokumisela umda wangoku iyahlengahlengiswa ukuze kunyuswe ukhetho lwe-inductor kwimfuno ethile yemveliso yangoku.Iinketho zexesha ezikhethiweyo nezilungelelaniswayo zokuqalisa ziquka ukulibaziseka okuncinci (akukho siqalo sithambileyo), ukumiswa ngaphakathi (900 µs), kunye nesiqalo esithambileyo esinocwangciso lwangaphandle usebenzisa i-capacitor.Isalathisi sePGOOD esivulekileyo sinokusetyenziselwa ulandelelwano, ingxelo yempazamo, kunye nokujongwa kwamandla ombane.I-LM5165 buck converter ifumaneka kwi-10-pin, 3-mm × 3-mm, iphakheji ye-VSON-10 ephuculwe ngokushushu kunye ne-0.5-mm pitch pitch.

Ukutshintsha abalawuli

1.Yintoni ukuTshintsha iiRegulators:
I-voltage regulator sisixhobo esenza i-voltage ephumayo izinzile kwaye iqulethe i-voltage regulator circuit, isiphaluka solawulo, kunye ne-servo motor.Xa igalelo lombane okanye umthwalo utshintsha, iisampulu zolawulo lwesekethe yomlawuli, uthelekisa kwaye ukhulise, kwaye emva koko uqhube i-servo motor ukujikeleza ukuze indawo ye-carbon brush yomlawuli itshintshe.Igcina i-voltage yemveliso izinzileyo ngokulungelelanisa ngokuzenzekelayo i-coil turns ratio.
I-switching regulator isetyenziselwa ukuvelisa i-voltage ephumayo ngokulawula i-transistor ukuba itshintshe phakathi kwe-ON state, kunye ne-OFF karhulumente kunye namacandelo okugcina amandla (i-capacitors kunye ne-inductors) ukugcina umbane uzinzile.Ihlengahlengiswa ngokulungelelanisa ixesha lokutshintsha ngokweesampuli zempendulo ye-voltage ephumayo.

Intshayelelo yomsebenzi

I-voltage regulator luhlobo lwesekethe yonikezelo lwamandla okanye izixhobo zokubonelela ngombane ezinokuhlengahlengisa ngokuzenzekelayo umbane wokuphuma.Indima yesilawuli sombane kukuguquguquka hayi ukuya kwiimfuno zezixhobo zombane ukuzinzisa amandla ombane kuluhlu lwexabiso elibekiweyo ukuze iindidi zeesekethe okanye izixhobo zombane zisebenze ngokwesiqhelo kumbane olinganisiweyo wokusebenza.

Ubungakanani besicelo

Isilawuli samandla ombane sinokusetyenziswa ngokubanzi kumashishini nakwimigodi, kumabala e-oyile, koololiwe, kwiindawo zokwakha, izikolo, izibhedlele, uphando lwezenzululwazi, kunye nezinye iindawo ezifuna uzinzo lombane wobonelelo lombane.Kwakhona iguqulelwe kwiikhomputha ze-elektroniki, izixhobo zomatshini ezichanekileyo, i-computer tomography (CT), izixhobo ezichanekileyo, izixhobo zokuvavanya, ukuphakamisa ukukhanya, izixhobo ezithunyelwa ngaphandle, imigca yokuvelisa kunye nezinye izixhobo.Ukongeza, i-voltage regulator ikwafanelekile kumbane ophantsi okanye ophezulu wonikezelo lwamandla, ukuguquguquka ekupheleni kwenethiwekhi yokuhambisa i-voltage ephantsi yabasebenzisi, kunye notshintsho lomthwalo kwizixhobo zamandla.Isilawuli samandla ombane silungele zonke iimfuno eziphakamileyo zozinziso lombane wegrid waveform yeendawo zamandla.Amandla aphezulu ahlawulela abalawuli bamandla banokudityaniswa kwi-thermal, i-hydraulic, kunye neejeneretha ezincinci.

Ukuhlelwa

Ngokohlobo olwahlukileyo lwemveliso yomlawuli, umlawuli wahlulwe ngokubanzi waba ngumlawuli we-AC (ubonelelo lwamandla ombane wokuzinzisa umbane we-AC) kunye nolawulo lwe-DC (ubonelelo lwamandla ombane wokuzinzisa i-DC) iindidi ezimbini.
Isilawuli sombane we-AC: isilawuli sombane sinamashumi amakhulu ukuya kumawaka eekilowathi ze-AC zolawulo lombane, kubonelelo lovavanyo olukhulu kunye neshishini, amandla okusebenza kwezixhobo zonyango.Kukwakho nezilawuli zombane ezincinci ze-AC zeewatts ezimbalwa ukuya kwiikilowathi ezimbalwa, ezelabhoratri ezincinci okanye izixhobo zasekhaya ukunika amandla omgangatho ophezulu.
Abalawuli be-DC: Ngokwemeko yokusebenza ye-tube yohlengahlengiso, abalawuli be-DC bahlala behlula ngamacandelo amabini: i-ware kunye nokutshintsha abalawuli.Ukutshintsha i-rectifier ye-regulator, i-smooth circuit ine-capacitor input type kunye ne-coil yokufaka uhlobo lwe-coil yeentlobo ezimbini, kufuneka iguquguquke ngokwendlela yesiphaluka yomlawuli wokutshintsha ukusebenzisa.Uhlobo lwegalelo le-coil choke lusetyenziswa kwii-step-down switching regulators, ngelixa uhlobo lwe-capacitor input lusetyenziswa kwi-step-up switching regulators.
Le mveliso isiguquli esisezantsi.
