♠ LM22675/-Q1 42 V, 1 I-SIMPLE SWITCHER® iNyathelo-Ezantsi i-Voltage Regulator eneempawu

I-LM22675 switching regulator ibonelela ngayo yonke imisebenzi eyimfuneko ukuze kuphunyezwe umlawuli osebenzayo wokunyuka kwamandla ombane aphezulu (i-buck) usebenzisa ubuncinci bamacandelo angaphandle.Oku kulula ukuyisebenzisa umlawuli udibanisa i-42 V N-channel MOSFET iswitshi ekwazi ukubonelela ukuya kwi-1 A yomthwalo wangoku.Umgca ogqwesileyo kunye nokulawulwa komthwalo kunye nokusebenza okuphezulu (> 90%) kubonisiwe.Ulawulo lwemowudi ye-voltage inika ubuncinci obufutshane ngexesha, ivumela umlinganiselo obanzi phakathi kwegalelo kunye nemveliso yombane.Imbuyekezo yelophu yangaphakathi ithetha ukuba umsebenzisi ukhululekile kumsebenzi odinayo wokubala amacandelo embuyekezo yeluphu.Ukulungiswa kwe-5 V yemveliso kunye nokukhethwa kwe-voltage ehlengahlengiswayo ekhoyo.I-frequency switching ye-500 kHz ivumela amacandelo amancinci angaphandle kunye nokuphendula okuhle kwexeshana.Ukuchaneka kwenza igalelo livumela ukwenziwa lula kolawulo lomlawuli kunye nolandelelwano lwamandla enkqubo.Kwimowudi yokuvala umlawuli uzoba kuphela i-25 µA (uchwethezo).Yakhelwe kwisiqalo esithambileyo (500 µs, isichwethezo) igcina amalungu angaphandle.I-LM22675 ikwakhelwe ukuvalwa kwe-thermal, kunye nokuthintela kwangoku ukukhusela ekugqithiseni ngengozi.

I-LM22675 lilungu losapho lwase-Texas Instruments'SIMPLE SWITCHER®.I-SIMPLE SWITCHER concept ibonelela ngokulula ukuyisebenzisa uyilo olupheleleyo usebenzisa inani elincinci lamacandelo angaphandle kunye nesixhobo sokuyila se-TI WEBENCH.Isixhobo se-WEBENCH se-TI sibandakanya iimpawu ezifana nokubala kwecandelo langaphandle, ukulinganisa kombane, ukulinganisa kwe-thermal, kunye neebhodi ze-Build-It ukuze kube lula ukuyila.
