Incazelo ye-TPS731

Umndeni we-TPS731xx wezilawuli zamandla kagesi womugqa we-TPS731xx usebenzisa i-topology entsha: isici sokudlula se-NMOS ekucushweni komlandeli kagesi.Le topology izinzile isebenzisa ama-output capacitor ane-low equivalent series resistance (ESR), futhi ivumela nokusebenza ngaphandle kwe-capacitor.Idivayisi iphinde inikeze ukuvinjelwa okuphezulu okubuyela emuva (isimanje esibuyela emuva esiphansi) kanye nephinikhodi yaphansi ecishe ibe njalo ngaphezu kwawo wonke amanani okukhiphayo wamanje.

I-TPS731xx isebenzisa inqubo ye-BiCMOS ethuthukisiwe ukuze inikeze ukunemba okuphezulu kuyilapho iletha ama-voltage aphansi kakhulu ayeka ukuphuma kanye nephinikhodi yomhlabathi ephansi.Ukusetshenziswa kwamanje, uma kungavunyelwe, kungaphansi kuka-1 µA futhi kulungele izinhlelo zokusebenza eziphathwayo.Umsindo ophumayo ophansi kakhulu (30 µV_I-RMSngo-0.1-µF C_NR) ilungele ukunika amandla ama-VCO.Lawa madivayisi avikelwe ukuvala shaqa okushisayo kanye nomkhawulo wamanje wokugoqa.

Okwedlule: I-UCC27531DBVR 35-V VDD, nokuhlukaniswa kwemiphumela

Olandelayo: TPS54140ADGQR 3.5V ukuya ku-42V Okokufaka

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

Bhala umlayezo wakho lapha futhi usithumelele wona
