LM22675/-Q1 42 V, 1 A fudud SWITCHER® Nidaamiyaha korantada ee Hoos-u-dhaca oo leh astaamo
Xakamaynta wareejinta LM22675 ayaa bixisa dhammaan shaqooyinka lagama maarmaanka u ah si loo hirgeliyo nidaam heer sare ah oo wax ku ool ah oo hoos u dhigaya (buck) iyada oo la adeegsanayo ugu yaraan qaybaha dibadda.Nidaamiyahan fudud ee loo isticmaali karo waxa uu ku darayaa 42 V N-channel MOSFET oo awood u leh in uu bixiyo ilaa 1 A ee culayska hadda.Xakamaynta qaabka korantada waxa ay bixisaa wakhtiga ugu yar ee wakhtiga, taas oo u ogolaanaysa saamiga ugu balaadhan ee u dhexeeya galinta iyo danabka wax soo saarka.Magdhawga wareegga gudaha macneheedu waa in isticmaaluhu uu xor ka yahay hawsha caajiska ah ee xisaabinta qaybaha magdhowga loop.Wax soo saarka 5 V ee go'an iyo fursadaha danab wax soo saarka la hagaajin karo ayaa diyaar ah.Inta jeer ee beddelka 500 kHz waxay u oggolaanaysaa qaybo yaryar oo dibadda ah iyo jawaab-celin ku-meel-gaar ah oo wanaagsan.Xaqiijinta awood gelinta waxay ogolaataa fududaynta xakamaynta nidaamiyaha iyo isku xigxiga awooda nidaamka.Habka xidhitaanka maamuluhu wuxuu sawiraa 25 µA (nooca).Lagu dhisay bilaw jilicsan (500 µs, nooca) waxay badbaadisaa qaybaha dibadda.LM22675 sidoo kale waxay ku dhistay xidhitaanka kulaylka, iyo xaddidaadda hadda si looga ilaaliyo culeyska shilalka ah.
LM22675 waa xubin ka tirsan qoyska Texas Instruments'SIMPLE SWITCHER®.Fikradda 'SIMPLE SWITCHER' waxay si fudud u isticmaali kartaa naqshad dhammaystiran iyadoo la adeegsanayo tirada ugu yar ee qaybaha dibadda iyo qalabka naqshadeynta TI WEBENCH.Qalabka TI ee WEBENCH waxa ku jira astaamo ay ka mid yihiin xisaabinta qaybaha dibadda, jilitaanka korantada, jilitaanka kulaylka, iyo looxyada Build-It ee qaabaynta fudud.
