Incazelo ye-LM22672
Isilawuli esishintshayo se-LM22672 sihlinzeka ngayo yonke imisebenzi edingekayo ukuze kusetshenziswe isilawuli sokudonsela phansi kwamandla kagesi aphezulu (ibhendi) sisebenzisa ubuncane bezingxenye zangaphandle.Lesi silawuli esisebenziseka kalula sihlanganisa ukushintshwa kwe-42 V N-channel MOSFET ekwazi ukunikeza kufikela kokungu-1 A komthwalo wamanje.Ulayini omuhle kakhulu nokulawulwa komthwalo kanye nokusebenza kahle okuphezulu (> 90%) kufakiwe.Ukulawulwa kwemodi ye-voltage kunikeza ubuncane besikhathi esifushane, okuvumela isilinganiso esikhulu kunazo zonke phakathi kwama-voltage okokufaka nokuphumayo.Isinxephezelo seluphu yangaphakathi sisho ukuthi umsebenzisi ukhululekile emsebenzini oyisicefe wokubala izingxenye zesinxephezelo seluphu.Okukhiphayo okungaguquki okungu-5 V kanye nezinketho zamandla kagesi eziguquguqukayo ziyatholakala.
Imvamisa yokushintsha ezenzakalelayo isethwe ku-500 kHz okuvumela izingxenye ezincane zangaphandle kanye nokusabela okuhle kwesikhashana.Ngaphezu kwalokho, i-frequency ingalungiswa phezu kwebanga lika-200 kHz ukuya ku-1 MHz nge-resistor eyodwa yangaphandle.I-oscillator yangaphakathi ingavumelaniswa newashi lesistimu noma ku-oscillator yomunye umlawuli.Ukunemba kokunika amandla okokufaka kuvumela ukwenziwa lula kokulawula isilawuli nokulandelana kwamandla esistimu.Kumodi yokuvala shaqa isilawuli sidonsa kuphela u-25 µA (uhlobo).Isici sokuqala esithambile esilungisekayo sinikezwa ngokukhethwa kwe-capacitor yangaphandle eyodwa.I-LM22672 futhi yakhelwe ekuvaleleni okushisayo, kanye nomkhawulo wamanje ukuvikela ekulayisheni ngengozi.
I-LM22672 iyilungu lomndeni we-Texas Instruments' SIMPLE SWITCHER®.Umqondo SIMPLE SWITCHER® uhlinzekela ukuklama okulula ukukusebenzisa kusetshenziswa inani elincane lezingxenye zangaphandle kanye nethuluzi lokuklama le-TI WEBENCH®.Ithuluzi le-TI's WEBENCH® lihlanganisa izici ezifana nokubala kwengxenye yangaphandle, ukulingisa ugesi, ukulingisa okushisayo, namabhodi e-Build-It ukuze kube lula ukuklama ngaphakathi.
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;Qondisa futhi uqondise 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 olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;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
