sharaxaad gaaban:

LMR16030 waa 60-V, 3-A FUDUD SWITCHER hoos-u-dejinta nidaamiye leh MOSFET dhinac sare ah oo isku dhafan.Iyada oo kala duwanaansho ballaadhan oo ka bilaabma 4.3 V ilaa 60 V, waxay ku habboon tahay codsiyada kala duwan ee warshadaha ilaa baabuurta qaboojinta korantada ee ilaha aan la xakameynin.Xakamaynta dabaylaha ee maamuluhu waa 40 µA qaabka hurdada, kaas oo ku habboon nidaamyada batteriga ku shaqeeya.1-µA aadka u hooseeya ee hadda ku jira qaabka xidhitaanka ayaa sii dheerayn kara nolosha batteriga.Kala duwanaanta soo noqnoqoshada beddelka ee ballaaran ee la isku hagaajin karo waxay u oggolaaneysaa waxtarka ama cabbirka ka kooban dibadda in la hagaajiyo.Magdhawga wareegga gudaha macneheedu waa in isticmaaluhu uu xor ka yahay hawsha caajiska ah ee naqshadaynta magdhowga loop.Tani waxay sidoo kale yaraynaysaa qaybaha dibadda ee qalabka.Xaqiijinta awood gelinta waxay ogolaataa fududaynta xakamaynta nidaamiyaha iyo isku xigxiga awooda nidaamka.Qalabku waxa kale oo uu leeyahay sifooyin ilaalin ku dhex dhisan sida meerta-wareeg xadka hadda jira, dareemaha kulaylka iyo xidhitaanka koronto xad dhaaf ah awgeed, iyo soosaarka ilaalinta xad-dhaafka ah.

Waa maxay Isku-xidhka Wareegga (IC)?

Ka hor inta aan la helin IC-yada, habka aasaasiga ah ee samaynta wareegyada waxay ahayd in la doorto qaybaha sida diodes, transistor, resistors, inductors iyo capacitors oo lagu xiro iyaga oo garbaha.Laakiin sababo la xiriira xajmiga iyo isticmaalka tamarta, waxay ahayd lagama maarmaan in la horumariyo wareegga cabbirka yar ee isticmaalka tamarta yar, kalsoonida iyo naxdinta.

Ka dib markii la abuuray semiconductors iyo transistor-ka, arrimuhu waa la fududeeyay ilaa xad gaar ah, laakiin horumarinta wareegyada isku dhafan ayaa beddelay wejiga tignoolajiyada elektiroonigga ah.Jack Kilby oo ka socda Texas Instruments iyo Bob Noyce oo ka socda Intel ayaa ah abuurayaasha rasmiga ah ee wareegyada isku dhafan, waxayna u sameeyeen si madaxbannaan.

Wareegga isku dhafan waa fikradda aasaasiga ah ee qalabka elektaroonigga ah oo ku dhisan fikrado kale oo aasaasi ah oo horay looga hadlay manhajkeena.Sidaa darteed, tixraac degdeg ah, u gudub maqaallada hoos ku taxan:

Faahfaahinta LMR16030

LMR16030 waa 60-V, 3-A FUDUD SWITCHER hoos-u-dejinta nidaamiye leh MOSFET dhinac sare ah oo isku dhafan.Iyada oo kala duwanaansho ballaadhan oo ka bilaabma 4.3 V ilaa 60 V, waxay ku habboon tahay codsiyada kala duwan ee warshadaha ilaa baabuurta qaboojinta korantada ee ilaha aan la xakameynin.Xakamaynta dabaylaha ee maamuluhu waa 40 µA qaabka hurdada, kaas oo ku habboon nidaamyada batteriga ku shaqeeya.1-µA aadka u hooseeya ee hadda ku jira qaabka xidhitaanka ayaa sii dheerayn kara nolosha batteriga.Kala duwanaanta soo noqnoqoshada beddelka ee ballaaran ee la isku hagaajin karo waxay u oggolaaneysaa waxtarka ama cabbirka ka kooban dibadda in la hagaajiyo.Magdhawga wareegga gudaha macneheedu waa in isticmaaluhu uu xor ka yahay hawsha caajiska ah ee naqshadaynta magdhowga loop.Tani waxay sidoo kale yaraynaysaa qaybaha dibadda ee qalabka.Xaqiijinta awood gelinta waxay ogolaataa fududaynta xakamaynta nidaamiyaha iyo isku xigxiga awooda nidaamka.Qalabku waxa kale oo uu leeyahay sifooyin ilaalin ku dhex dhisan sida meerta-wareeg xadka hadda jira, dareemaha kulaylka iyo xidhitaanka koronto xad dhaaf ah awgeed, iyo soosaarka ilaalinta xad-dhaafka ah.

LMR16030 waxaa lagu heli karaa xirmo 8-pin ah oo HSOIC ah oo leh suuf daboolan oo iska caabbinta kulaylka hooseeya.

Badeecada cusub, LM76003, waxay u baahan tahay qaybo dibadda ah oo aad u yar waxayna leedahay pinout loogu talagalay fudud, qaabaynta PCB ugu fiican ee EMI iyo waxqabadka kulaylka.Eeg miiska isbarbardhigga aaladda si aad u barbar dhigto faahfaahinta.
