Inkcazelo ye-LM5160

I-LM5160/A yi-65-V,2-A i-synchronous step-down converter kunye ne-MOSFETs edibeneyo ehlangeneyo kunye necala eliphantsi.I-adaptive ye-adaptive ye-time control scheme ayifuni imbuyekezo ye-loop kwaye ixhasa umlinganiselo ophezulu wokuhla kunye nokuphendula ngokukhawuleza okwethutyana.I-feedbackamplifier yangaphakathi igcina i-± 1% yolawulo lwe-voltage yemveliso kulo lonke uluhlu lobushushu bokusebenza.Ixesha le-Theon liyahluka ngokungafaniyo kunye ne-voltage yegalelo ekhokelela kwi-switchingfrequency phantse rhoqo.

Incopho kunye nentlambo imida imijikelezo yangoku zikhusela kwiimeko zokugcwala.I-Theundervoltage lockout (EN/UVLO) isekethe ibonelela ngokuzimeleyo igalelo elihlengahlengiswayo elingaphantsi komthamo kunye ne-hysteresis.I-LM5160/A icwangciswe ngepini ye-FPWM ukuba isebenze kwimodi yokuqhubela phambili (CCM) ukusuka kungabikho mthwalo ukuya kumthwalo opheleleyo okanye ukutshintshela ngokuzenzekelayo kwimodi ye-discontinuousconduction (DCM) kumthwalo wokukhanya ukuze usebenze kakuhle.Umsebenzi onyanzelweyo we-CCM uxhasa iziphumo ezininzi kunye nosetyenziso olulodwa lweFly-Buck kusetyenziswa i-inductor edibeneyo.

I-LM5160A yabelana ngeempawu ezifanayo kunye noqwalaselo lwepin njenge-LM5160.Ukunikezelwa kwe-bias yangaphandle kunokudibaniswa kwi-pin ye-VCC ye-LM5160A kwi-Buck kunye ne-Fly-Buckapplications.Lo mandla ongezelelweyo wehlisa ukuchithwa kwamandla e-IC kwaye uphucula ukusebenza kakuhle kwe-athigh input voltages.

  • Okulandelayo:

  • 1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?

    -R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.

    Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo

    Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani

     

    2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?

    -Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
