♠ LM22675/-Q1 42 V, 1 A SIMPLE SWITCHER® Isilawuli sikagesi esiya Phansi esinezici
Isilawuli esishintshayo se-LM22675 sihlinzeka ngayo yonke imisebenzi edingekayo ukuze kusetshenziswe isilawuli sokudonsela phansi kwamandla kagesi aphezulu (ibhendi) sisebenzisa ubuncane bezingxenye zangaphandle.Lesi silawuli esisebenziseka kalula sihlanganisa ukushintshwa kwe-42 V N-channel MOSFET ekwazi ukunikeza kufika ku-1 A yomthwalo wamanje. Ulayini omuhle kakhulu nokulawulwa komthwalo kanye nokusebenza kahle okuphezulu (> 90%) kufakiwe.Ukulawulwa kwemodi ye-voltage kunikeza ubuncane besikhathi esifushane, okuvumela isilinganiso esikhulu kunazo zonke phakathi kwama-voltage okokufaka nokuphumayo.Isinxephezelo seluphu yangaphakathi sisho ukuthi umsebenzisi ukhululekile emsebenzini oyisicefe wokubala izingxenye zesinxephezelo seluphu.Okukhiphayo okungaguquki okungu-5 V kanye nezinketho zamandla kagesi eziguquguqukayo ziyatholakala.Imvamisa yokushintsha engu-500 kHz ivumela izingxenye ezincane zangaphandle kanye nokusabela okuhle kwesikhashana.Ukunemba kokunika amandla okokufaka kuvumela ukwenziwa lula kokulawula isilawuli nokulandelana kwamandla esistimu.Kumodi yokuvala shaqa isilawuli sidonsa u-25 µA kuphela (uhlobo).Isiqalo esithambile esakhelwe ngaphakathi (500 µs, uhlobo) silondoloza izingxenye zangaphandle.I-LM22675 futhi yakhelwe ekuvaleleni okushisayo, kanye nomkhawulo wamanje ukuvikela ekulayisheni ngengozi.
I-LM22675 iyilungu lomndeni we-Texas Instruments'SIMPLE SWITCHER®.I-SIMPLE SWITCHER mqondo ihlinzekela ukuklama okulula ukukusebenzisa kusetshenziswa inani elincane lezingxenye zangaphandle kanye nethuluzi lokuklama le-TI WEBENCH.Ithuluzi le-TI's WEBENCH lihlanganisa izici ezifana nokubala kwengxenye yangaphandle, ukulingisa kukagesi, ukulingisa okushisayo, namabhodi e-Build-It ukuze kube lula ukuklama ngaphakathi.
