Iyini i-Integrated Circuit (IC)?

Ngaphambi kokutholwa kwama-IC, indlela eyisisekelo yokwenza amasekhethi kwakuwukukhetha izakhi ezifana nama-diode, ama-transistors, ama-resistors, ama-inductors nama-capacitor bese uwaxhuma ngokuwabeka emahlombe.Kodwa ngenxa yobukhulu nezinkinga zokusetshenziswa kwamandla, kwakudingeka ukuthi kuthuthukiswe isekethe yosayizi omncane esebenzisa amandla amancane, ukwethembeka kanye ne-shockproof.

Ngemva kokusungulwa kwama-semiconductors nama-transistors, izinto zenziwa lula ngokwezinga elithile, kodwa ukuthuthukiswa kwamasekethe ahlanganisiwe kwashintsha ubuso bobuchwepheshe be-electronics.UJack Kilby waseTexas Instruments kanye noBob Noyce wase-Intel bangabadali abasemthethweni bamasekethe ahlanganisiwe, futhi bakwenza ngokuzimela.

Isekethe ehlanganisiwe ingumqondo oyisisekelo wezinto zikagesi owakha phezu kweminye imiqondo eyisisekelo okwaxoxwa ngayo ngaphambilini kusilabhasi yethu.Ngakho-ke, ukuze uthole ireferensi esheshayo, bheka izihloko ezibalwe ngezansi:

Incazelo ye-LMR16030

I-LMR16030 iyisilawuli sokuya phansi esingu-60-V, 3-A SIMPLE SWITCHER esine-MOSFET ehlangene yohlangothi oluphezulu.Ngobubanzi bokufakwayo okubanzi kusuka ku-4.3 V kuya ku-60 V, ilungele izinhlelo zokusebenza ezihlukahlukene kusukela ezimbonini kuya ezimotweni zokulungiswa kwamandla kusuka emithonjeni engalawulwa.Ukuthula kwesilawuli kungu-40 µA kumodi yokulala, elungele amasistimu asebenza ngebhethri.I-ultra-low 1-µA yamanje kumodi yokuvala shaqa ingaqhubeka endebe impilo yebhethri.Ibanga lefrikhwensi yokushintsha elilungisekayo elibanzi livumela ukusebenza kahle noma usayizi wengxenye yangaphandle ukuthi uthuthukiswe.Isinxephezelo seluphu yangaphakathi sisho ukuthi umsebenzisi ukhululekile emsebenzini oyisicefe wokuklama isinxephezelo seluphu.Lokhu futhi kunciphisa izingxenye zangaphandle zedivayisi.Ukunemba kokunika amandla okokufaka kuvumela ukwenziwa lula kokulawula isilawuli nokulandelana kwamandla esistimu.Idivayisi futhi inezici zokuvikela ezakhelwe ngaphakathi ezifana nomkhawulo wamanje womjikelezo nomjikelezo, inzwa yokushisa nokuvalwa ngenxa yokushabalaliswa kwamandla amaningi, nokuvikelwa kokukhishwa kwe-voltage.

I-LMR16030 itholakala kuphakeji ye-HSOIC yamaphini angu-8 enephedi eveziwe yokumelana nokushisa okuphansi.

Umkhiqizo omusha, i-LM76003, udinga izingxenye zangaphandle ezimbalwa kakhulu futhi unophinikhodi oklanyelwe ukwakheka kwe-PCB okulula, okuphelele kwe-EMI nokusebenza okushisayo.Bona ithebula lokuqhathanisa ledivayisi ukuze uqhathanise imininingwane.
