Njengenxalenye ephambili kwinkqubo ye-elektroniki yobunjineli bamandla, i-IC ye-transformer yamandla isetyenziswe ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki. Inokubaluleka okubonakalayo okubalulekileyo ekuqinisekiseni ukusebenza okuthembekileyo kweemveliso ze-elektroniki kunye nokuphumeza ukonga nokunciphisa ukusetyenziswa kwamandla. Kwiminyaka yakutshanje, imboni yokuvelisa i-IC ye-transformer yamandla igcine i-high-aspect ratio yothando kutyalo-mali lweprojekthi. Kwelinye icala, ngenxa yokuthontelana okuqhubekayo kwabangeneli abatsha kunye nokwanda kwemfuno yentengiso, ezinye iinkampani kwishishini lemveliso ezinamandla onke aqinileyo zilindele ukufumana inzuzo yentsebenziswano yezoqoqosho esekwe kumanyano olubanzi lweenkampani kunye nokufunyanwa ukwenza inkampani ejikeleze isixeko; kwelinye icala, kunye nezithuthi zaMandla amatsha kunye namanye amashishini okuvelisa acandekileyo aqhubeka nokuphuhlisa ngokukhawuleza, kwaye indawo yangaphakathi kwintengiso yentengiso yeshishini lemveliso ikhula ngokuthe ngcembe. Iinkampani ezininzi zijonge phambili ekukhetheni olu setyenziso luphambili ngokweendlela ezinjengotyalo-mali lweprojekthi kunye nokudityaniswa kweenkampani kunye nokuzuza ukufumana ukhuphiswano olungundoqo.
Nangona i-China i-transformer yamandla yokuvelisa i-IC inabathathi-nxaxheba abaninzi, isahluke kakhulu kubavelisi baseYurophu nabaseMelika malunga nomlinganiselo wekhonkco loshishino kunye nokukhuphisana kweemveliso eziphezulu; ukuba abavelisi belizwe laseTshayina bafuna ukujoyina iqela elikhokelayo, kufuneka baqale baphendule Idabi lexesha elide elifuna zombini imali kunye neetalente. I-Shenzhen China UnionPay Automation Technology Co., Ltd. ineminyaka engama-20 yobuchule bobugcisa kwi-teknoloji ye-IC ye-transformer yamandla, i-asethi eyomeleleyo iyonke kunye nomgangatho wenkonzo yodidi lokuqala. Wamkelekile ukuthetha.
Uphuhliso lwemveliso entsha ye-China ye-UnionPay yeTekhnoloji kunye nemveliso ivelise i-U6235 yamandla e-IC ye-transformer ene-VDD esezantsi yombane osebenza ngokuzimeleyo umsebenzi wenkqubo, kwaye i-transformer inokususa i-winging encedisayo. U6235 uguqulo lwamandla IC luphezulu olusebenzayo oluphambili olulawulwa yimveliso yamandla ombane, olunokuthi lubonise iimpawu zemveliso yomthombo ochanekileyo ochanekileyo okhoyo ngoku kunye nomthombo wamandla okhoyo ngoku, ngokukodwa ukulungele ukusetyenziswa kwentloko ephantsi yemveliso yombane kunye Izibane zeKrisimesi ze-LED.
U6235 iinzuzo ze-IC yesiguquli samandla:
1. Ngomsebenzi wenkqubo ye-VDD ephantsi kwamandla ombane, i-transformer inokususa i-winging encedisayo
2. Unesiphumo sokuvula ngokukhawuleza
3. Qala ngomsebenzi we-LineBOP
4. Edityanisiweyo 800V amandla ombane aphezulu ophumayo BJT
5.±5% unikezelo lwamandla lwangoku oluqhubekayo, ukuchaneka komthombo wangoku rhoqo
6. Indlela yokulawula icala eliphambili elineendlela ezininzi
7. Akukho sandi emsebenzini
8. Imbuyekezo yelahleko ehlengahlengiswayo
9. Imbuyekezo yamandla akhoyo rhoqo kunye nombane wesigaba esidibeneyo kunye nombane osebenzayo womthwalo
10. Umsebenzi odibeneyo kunye nokugcinwa kwesandi:
11. Ukhuseleko lwangoku (SLP)
12. Ukhuseleko ngaphezulu kobushushu (OTP)
13. Ulondolozo lwexesha lomjikelo ngokungaphaya kokhuseleko (OCP)
I-14.FB phezu kokhuseleko lombane (FBOVP)
15. Ukhuseleko lwesigaba sokuqalisa umbane ongaphantsi kombane (LineBOP)
I-16.VDD phezu kokhuseleko lombane
17. Uhlobo lwephakheji SOP-7
I-IC ye-U6235 ye-transformer yamandla iqulethe imodyuli yokulawula inkqubo ye-VDD ephantsi kwamandla ombane, efanelekileyo kwi-architecture ye-PSR ene-windings ezimbini. Kwakhona kunomsebenzi wokuvula ngokukhawuleza, okuvumela i-VDD ukuba ikhethe indawo enkulu (22uF okanye 30uF) i-electrolytic capacitor, ekhuthaza ukunikezelwa kwamandla okutshintsha kunokuhlanganiswa kwizicelo ze-ultra-low ezifana nezibane zeKrisimesi ze-LED. I-U6235 nayo inomsebenzi wokukhusela i-voltage yesigaba esingaphantsi kwe-voltage ekuqaliseni, enokuthi ithintele i-PSR ekufumaneni imeko yokusebenza engaqhelekanga xa i-voltage yesigaba iphantsi kakhulu.
