Incazelo ye-LM5160
I-LM5160/A iyisiguquli se-65-V,2-A esivumelanayo sokuya phansi esinama-MOSFET ahlanganisiwe anohlangothi oluphezulu naphansi.Isikimu sokulawula okuguquguqukayo esisebenza ngesikhathi asidingi isinxephezelo se-loop futhi sisekela izilinganiso eziphakeme zokusuka phansi kanye nempendulo yesikhashana esheshayo.Isiamplifier sangaphakathi sigcina ukulawulwa kwamandla kagesi angu-±1% kulo lonke ibanga lokushisa lokusebenza.I-Theon-time iyahlukahluka ngokuphambene ne-voltage yokufaka okuholela ekushintsheni okungashintshi kwefrequency.
Amasekhethi omkhawulo wamanje aphezulu kanye nesigodi avikela ezimeni zokugcwala ngokweqile.Isekethe ye-Theundervoltage lockout (EN/UVLO) ihlinzeka ngokuzimele okuguquguqukayo okokufaka kwe-undervoltagethreshold kanye ne-hysteresis.I-LM5160/A ihlelwe ngephinikhodi ye-FPWM ukuze isebenze kumodi yokuqhuba okuqhubekayo (CCM) isuke lapho kungekho mthwalo ukuya ekulayisheni okugcwele noma ishintshele kumodi ye-discontinuousconduction (DCM) ekulayisheni ukukhanya ukuze isebenze kahle kakhulu.Ukusebenza okuphoqiwe kwe-CCM kusekela okuphumayo okuningi kanye nezinhlelo zokusebenza ezizimele ze-Fly-Buck kusetshenziswa i-inductor ehlanganisiwe.
I-LM5160A yabelana ngezici ezifanayo nokucushwa kwephini njenge-LM5160.Ukunikezwa kokuchema kwangaphandle kungaxhunywa kuphinikhodi ye-VCC ye-LM5160A ku-Buck and Fly-Buckapplications.Leli khono elengeziwe lehlisa ukuchithwa kwamandla e-IC futhi lithuthukisa ukusebenza kahle kokufakwayo kwe-athigh.
1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?
-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Liqondise futhi liqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.
Umphathi we-R & D: yenza uhlelo lwe-R & D lomkhiqizo omusha futhi ubonise ukuba nokwenzeka kohlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene
Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo
2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?
- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
