Incazelo ye-TPS62147
I-TPS62147 ne-TPS62148 zisebenza kahle kakhulu futhi kulula ukuzisebenzisa iziguquli zesinyathelo-downDC/DC ezivunyelanisiwe, ngokusekelwe ku-DCS-Control™Topology.Ububanzi bamandla kagesi okufakwayo obubanzi obungu-3-V ukuya ku-17-V bubenza bafanelekele i-Li-Ion enamaseli amaningi kanye nama-12-V ama-intermediate supply rails.Amadivayisi ahlinzeka ngo-2-A ophumayo oqhubekayo wamanje.Bangena ngokuzenzakalelayo Imodi Yokonga Amandla ekulayishweni okulula ukuze bagcine ukusebenza kahle okuphezulu kulo lonke ibanga lokulayisha.Ngalokho, zifaneleka kahle izinhlelo zokusebenza ezidinga ukusebenza okulindile okuxhunyiwe, njenge-PC yezimboni nokubhekwa kwevidiyo.Njengoba iphinikhodi ye-MODE isethelwe phansi, i-switchingfrequency ishintshwa ngokuzenzakalelayo ngokusekelwe kokuphumayo kwamanje kanye nakuma-input kanye ne-outputvoltage.Le nqubo ibizwa ngokuthi i-Automatic Efficiency Enhancement (AEE™) futhi igcina ukusebenza kahle kokuguqulwa okuphezulu kulo lonke ibanga lokusebenza.I-TPS62147, TPS62148 ihlinzeka ngokunemba kwe-outputvoltage engu-1% kumodi ye-PWM futhi ngenxa yalokho inike amandla ukuklanywa komthombo wamandla ngokunemba okuphezulu kwe-outputvoltage.Iphinikhodi ye-FSEL ivumela ukusetha imvamisa yokushintsha kwimodi ye-PWM ephoqelelwe engu-1.25 MHz noma 2.5 MHz, ngokulandelanayo.
Umoya othule ojwayelekile ungu-18 µA.Kumodi yokuvala shaqa okwamanje imvamisa ingu-1µA.
Amadivayisi ayatholakala njengenguqulo elungisekayo, epakishwe ku-VQFNpackage engu-3-mm × 2-mm.
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
