Incazelo ye-TPS53319
Amadivayisi we-TPS53318 kanye ne-TPS53319 ayimodi ye-D-CAP, i-8-A noma i-14-A eshintshashintshayo yama-synchronous nama-MOSFET ahlanganisiwe.Zenzelwe ukusetshenziswa kalula, isibalo esiphansi sezingxenye zangaphandle, namasistimu anamandla aqaphela isikhala.
Lawa madivayisi afaka u-1% onembile, ireferensi engu-0.6-V, kanye neswishi ye-boost ehlanganisiwe.Isampula yezici ezincintisanayo ihlanganisa: 1.5-V kuya ku-22-V ububanzi bevoltheji yokufaka yokuguqula, ukubalwa kwengxenye yangaphandle ephansi kakhulu, ukulawulwa kwemodi ye-D-CAP™ yesikhashana esishesha kakhulu, ukusebenza kwemodi yokweqa okuzenzakalelayo, isilawuli sokuqala esithambile sangaphakathi, okukhethekayo imvamisa, futhi asikho isidingo sokunxeshezelwa.
I-voltage yokufaka yokuguqula isuka ku-1.5 V iye ku-22 V, i-supply voltage range isuka ku-4.5 V iye ku-25 V, kanti ububanzi bamandla okukhiphayo busuka ku-0.6 V kuye ku-5.5 V.
Lawa madivayisi atholakala ngephakheji ye-QFN engu-5 mm x 6 mm, amaphini angu-22 futhi acaciswe ukusuka ku- –40°C kuya ku-85°C.
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
