Izinzuzo zethu

Izinqubo zokukhiqiza zaseShayina ziye zabhekana neminyaka yokuphindaphinda, okuholele kubuchwepheshe obuvuthiwe nobuthembekile. Izinkampani eziningi zamazwe ngamazwe zikhetha ukukhiqiza ukukhiqiza eChina. Njengomkhiqizi wezingxenye ze-elekthronikhi e-China, imikhiqizo yethu ingangena esikhundleni ngokuphelele semikhiqizo emikhulu yamazwe ngamazwe kuma-99% wezinhlelo zokusebenza ngaphandle kwesidingo sokuqinisekisa ukuhlolwa. Imikhiqizo yethu iqhosha ngokungaguquguquki okuphezulu ngekhwalithi, amanani entengo aphusile, i-inventory eyanele, ukunikezwa okuvumelana nezimo, izikhathi zokuhola ezimfishane, kanye nesevisi yobungcweti ngemva kokuthengisa. 

Incazelo Yomsebenzi
I-SL4275 iyisilawuli se-voltage esingaguquki esihlanganisiwe se-monolithically kuphakheji ye-5-pin TO. Amandla okokufaka afika ku-55V alawulwa ku-voltage ephumayo engu-VQ engu-5.0V. I-chip ingashayela umthwalo ongu-450mA futhi inokuvikelwa kwesekethe emfushane kanye nokuvikela okungaphezulu kwezinga lokushisa. Uma i-voltage ephumayo ye-VQ iphansi kunevelu evamile engu-4.65V, iphinikhodi ye-RQ ye-chip izokhiqiza isignali yokusetha kabusha yezinga eliphansi, futhi isikhathi sokulibaziseka sokusetha kabusha singasethwa yi-D pin delay capacitor.

Ulwazi lwengxenye yangaphandle
I-SL4275 idinga i-input capacitor CI ukunxephezela imiphumela yokulandelela. Ukuze uqinisekise ukuzinza kwesifunda sokulawula, i-CQ capacitor ephumayo iyadingeka. Ama-Capacitor okukhiphayo ane-CQ≥ 22uF ne-ESR ≤ 5Ω aqinisekisa ukuzinza ebangeni lokushisa elisebenzayo.

Incazelo yesifunda
I-op amp yokulawula iqhathanisa i-voltage eyireferensi ne-voltage ngokulingana ne-voltage ephumayo futhi ishayela isango lochungechunge lwe-MOS transistor ngokusebenzisa ibhafa. Ngaphezu kwalokho, iyunithi yokulawula ekhawulelwe yamanje yomthwalo wamanje ivimbela ukugcwala ngokweqile kwezingxenye zamandla. I-chip iphinde ihlanganise amasekhethi amaningi angaphakathi ukuze alayishe ngokweqile, izinga lokushisa elingaphezu kwamandla, nokunye ukuvikela.

Izici
● I-voltage ephumayo elinganiselwe engu-5V, ububanzi bokunemba ±2%
● Ukusetshenziswa kwamandla aphansi kakhulu: 80uA
● Ukukhanyisa nokuphuma Kabusha okuBrown
● Ukwehla okuphansi
● Ukuvikela isifunda esifushane
● RoHS

Izicelo

● I-Automotive Electronics: Ihlinzeka nge-voltage ezinzile yezilawuli ezincane, izinzwa, nama-actuator kumasistimu ezimoto.

● Ukulawulwa Kwemboni: Ukunika amandla amasekhethi okulawula, izinzwa, namamojula okuxhumana kumishini ezenzakalelayo yezimboni.

● I-Consumer Electronics: Ukuqinisekisa ukutholakala kwamandla kagesi okuzinzile kumadivayisi anamandla ebhethri namasekhethi okushaja.

● Ezokuxhumana: Ukugcina amazinga kagesi angashintshi ezisetshenziswa zenethiwekhi namadivayisi okuxhumana.
