Incazelo ye-TPS40200
I-TPS40200 iyisilawuli esivumelana nezimo, esingavumelanisi esinomshayeli owakhelwe ngaphakathi we-200-mA wama-P-channel FET.Isekhethi isebenza nama-inputs afika ku-52 V anezici zokonga amandla ezicisha i-driver current uma i-FET yangaphandle isivulwe ngokugcwele.Lesi sici sinweba ukuguquguquka kwedivayisi, siyivumele ukuthi isebenze nge-voltage yokufaka efika ku-52 V ngaphandle kokulahla amandla amaningi.Isekhethi isebenza ngempendulo yemodi ye-voltage futhi inesinxephezelo samandla kagesi okufakwayo okudlulisela phambili esiphendula ngokushesha ekushintsheni kokufakwayo kagesi.Ireferensi ebalulekile ye-700-mV isikwe yafinyelela ku-2%, ihlinzeka ngezindlela zokulawula ngokunembile ama-voltage aphansi.I-TPS40200 itholakala nge-SOIC engu-8-pin kanye nephakheji ye-VSON engu-8 futhi isekela izici eziningi zezilawuli eziyinkimbinkimbi.Ukuvama kwewashi, ukuqala okuthambile, kanye nemikhawulo ye-overcurrent ngayinye ihlelwa kalula ngengxenye eyodwa, yangaphandle.Ingxenye inokukhiya ngaphandle kwe-voltage, futhi ingavunyelaniswa kalula kwezinye izilawuli noma iwashi lesistimu ukwanelisa izimfuneko zokulandelana kanye/noma zokunciphisa umsindo.
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
