Incazelo ye-TPS54140A

Idivayisi ye-TPS54140A iyi-42-V, 1.5-A, isilawuli sokusuka phansi esine-MOSFET ehlangene yohlangothi oluphezulu.Ukulawula imodi yamanje kunikeza isinxephezelo esilula sangaphandle nokukhetha kwengxenye evumelana nezimo.Imodi yokweqa i-ripple-pulse ephansi yehlisa ukungalayishi, okulawulwayo okunikezwayo kokukhiphayo okwamanje kuya ku-116 µA.Ngokusebenzisa iphinikhodi, amandla okunikezwayo okuvala shaqa ancishiswa abe ngu-1.3 µA.

I-Undervoltage lockout isethwe ngaphakathi kokuthi 2.5 V, kodwa inganyuswa kusetshenziswa iphinikhodi yokunika amandla.Irempu yokuqala kagesi ephumayo ilawulwa iphinikhodi yokuqala enensayo engalungiselelwa ukulandelana/ukulandelela.Isignali enhle yamandla okukhipha amanzi ikhombisa ukuthi ukuphuma kungaphakathi kuka-94% kuya ku-107% wevolthi yayo encane.

Ububanzi befrikhwensi yokushintsha ebanzi buvumela ukusebenza kahle kanye nosayizi wengxenye yangaphandle ukuthi uthuthukiswe.Imvamisa ukugoqa emuva kanye nokuvala shaqa okushisayo kuvikela ingxenye ngesikhathi sokugcwala kakhulu.

Okwedlule: I-TPS73133DBVR 150-mA, ukunemba okuphezulu

Olandelayo: I-OPA4322AIPWR Quad, 5.5-V, 20-MHz

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
