Inkcazelo ye-LM22672
I-LM22672 switching regulator ibonelela ngayo yonke imisebenzi eyimfuneko ukuphumeza isilawuli esisebenzayo sokunyuka kwamandla ombane aphezulu (i-buck) usebenzisa ubuncinci bamacandelo angaphandle.Oku kulula ukuyisebenzisa umlawuli udibanisa i-42 V N-channel MOSFET iswitshi ekwaziyo ukubonelela ukuya kwi-1 A yomthwalo wangoku.Umgca ogqwesileyo kunye nolawulo lomthwalo kunye nokusebenza kakuhle 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 frequency ibekwe kwi-500 kHz ivumela amacandelo amancinci angaphandle kunye nokuphendula okuhle kwexeshana.Ukongeza, i-frequency inokulungiswa kuluhlu lwe-200 kHz ukuya kwi-1 MHz kunye ne-resistor enye yangaphandle.I-oscillator yangaphakathi inokulungelelaniswa kwiwashi yenkqubo okanye kwi-oscillator yomnye umlawuli.Ukuchaneka kwenza igalelo livumela ukwenziwa lula kolawulo lomlawuli kunye nolandelelwano lwamandla enkqubo.Kwimowudi yokuvala umlawuli uzoba kuphela i-25 µA (uchwethezo).I-softable-start-start feature inikezelwa ngokukhethwa kwe-capacitor enye yangaphandle.I-LM22672 ikwakhelwe ukuvalwa kwe-thermal, kunye nokunciphisa umda wangoku ukukhusela ekugqithiseni ngengozi.
I-LM22672 lilungu losapho lwe-Texas Instruments' SIMPLE SWITCHER®.I-SIMPLE SWITCHER® ingqikelelo ibonelela ngokulula ukuyisebenzisa uyilo olupheleleyo usebenzisa ubuncinci bezinto zangaphandle kunye ne-TI WEBENCH® isixhobo soyilo.Isixhobo se-TI sika-WEBENCH® sibandakanya iimpawu ezifana nokubala kwecandelo langaphandle, ukulinganisa kombane, ukulinganisa kwe-thermal, kunye neebhodi ze-Build-It ukuze kube lula ukuyila.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
