LM5165YDRCR Ibikoresho bya elegitoronike Ibice IC Byinjijwemo Chip Mububiko

ibisobanuro bigufi:

Igikoresho cya LM5165 nikintu cyoroshye, cyoroshye-gukoresha, 3-V kugeza 65-V, ultra-low IQ synchronous buck ihindura hamwe nubushobozi buhanitse hejuru yumurongo mugari winjiza kandi uremerera urwego rugezweho.Hamwe na MOSFETs ihuriweho cyane-hamwe na-MASFETs, kugeza kuri 150-mA yumusaruro ushobora gutangwa kuri voltage yagenwe ya 3.3 V cyangwa 5 V cyangwa kumusaruro uhinduka.Ihindura ryashizweho kugirango ryorohereze ishyirwa mubikorwa mugihe ritanga amahitamo yo kunoza imikorere kubikorwa bigenewe.Uburyo bwa Pulse Frequency Modulation (PFM) bwatoranijwe kuburyo bwiza bwumucyo-umutwaro cyangwa guhora ku gihe (COT) kugenzura hafi yumurimo uhoraho.Gahunda zombi zo kugenzura ntizisaba indishyi zuzuye mugihe zitanga umurongo mwiza kandi uremereye igisubizo cyigihe gito hamwe na PWM ngufi mugihe kinini kinini cyo guhinduka.

Ibicuruzwa

Uruhande rwo hejuru P-umuyoboro MOSFET irashobora gukora kuri 100% yumusoro kuri voltage ntoya kandi ntisaba ubushobozi bwa bootstrap capacitor yo gutwara amarembo.Na none, imipaka igezweho irashobora guhindurwa kugirango ihindure inductor yo guhitamo ibisohoka byubu bisabwa.Guhitamo no guhindurwa gutangira igihe cyo guhitamo harimo gutinda byibuze (nta gutangira byoroshye), gukosorwa imbere (900 µs), hamwe na progaramu yo hanze ishobora gutangira ukoresheje capacitor.Gufungura-imiyoboro ya PGOOD irashobora gukoreshwa mugukurikirana, gutanga amakosa, no kugenzura ingufu za voltage.LM5165 ihindura buck iraboneka muri 10-pin, 3-mm × 3-mm, yongerewe ubushyuhe bwa VSON-10 hamwe na 0.5-mm pin.

Guhindura Abagenzuzi

1.Ni iki Guhindura Abagenzuzi:
Igenzura rya voltage nigikoresho gituma ibisohoka biva mumashanyarazi bihamye kandi bigizwe numuzunguruko wa voltage, umuzenguruko, na moteri ya servo.Iyo ibyinjijwe na voltage cyangwa imitwaro bihindutse, umugenzuzi agenzura ingero zumuzunguruko, agereranya kandi akongerera imbaraga, hanyuma agatwara moteri ya servo kuzunguruka kugirango umwanya wa brux ya karubone uhindurwe.Igumya gusohora voltage ihagaze muguhita uhindura igipimo cya coil.
Igikoresho cyo guhinduranya gikoreshwa mu kubyara ingufu ziva mu kugenzura transistor kugirango ihindurwe hagati ya leta ya ON, na leta ya OFF hamwe nibikoresho bibika ingufu (capacator na inductor) kugirango voltage ikomeze.Byahinduwe muguhindura igihe cyo guhinduranya ukurikije ibisubizo byicyitegererezo cyibisohoka voltage.

Intangiriro

Igenzura rya voltage ni ubwoko bwumuriro wumuriro cyangwa ibikoresho bitanga amashanyarazi bishobora guhita bihindura ibyasohotse mumashanyarazi.Uruhare rwumubyigano wa voltage nuguhindagurika kandi ntujuje ibisabwa nibikoresho byamashanyarazi kugirango uhagarike amashanyarazi mumashanyarazi yagenwe kugirango imiyoboro itandukanye cyangwa ibikoresho byamashanyarazi bishobora gukora mubisanzwe kuri voltage ikora.

Igipimo cyo gusaba

Igenzura rya voltage rirashobora gukoreshwa cyane mubucuruzi bwinganda nubucukuzi bwamabuye y'agaciro, imirima ya peteroli, gari ya moshi, ahazubakwa, amashuri, ibitaro, ubushakashatsi bwa siyansi, nahandi hantu hakenera ingufu z'amashanyarazi.Yahujwe kandi na mudasobwa ya elegitoronike, ibikoresho bya mashini isobanutse, tomografi ya mudasobwa (CT), ibikoresho bisobanutse, ibikoresho byo gupima, amatara yo kuzamura, ibikoresho bitumizwa mu mahanga, imirongo y’ibicuruzwa, nibindi bikoresho.Mubyongeyeho, igenzura rya voltage naryo rirakwiriye kumashanyarazi make cyangwa menshi yo gutanga amashanyarazi, ihindagurika kumpera yumuyoboro muke wo gukwirakwiza abakoresha, hamwe no guhindura imitwaro mubikoresho byamashanyarazi.Igenzura rya voltage rirakenewe cyane cyane kubisabwa byose hejuru ya gride waveform ya voltage ihindagurika yumuriro.Amashanyarazi menshi yishyuza amashanyarazi arashobora guhuzwa nubushyuhe, hydraulic, na generator nto.

Ibyiciro

Ukurikije imiterere itandukanye yumusaruro wubuyobozi, mugenzuzi muri rusange agabanijwemo AC igenzura (AC voltage stabilisation power power) hamwe na DC (DC voltage stabilisation power power) ibyiciro bibiri.
Igenzura rya AC voltage: igenzura rya voltage rifite ibilometero icumi kugeza ku bihumbi kilowatts ya AC voltage igenzura, ni ugutanga amashanyarazi manini yubushakashatsi ninganda, ibikoresho byubuvuzi.Hariho kandi amashanyarazi mato mato ya AC ya watt nkeya kuri kilowatt nkeya, arizo za laboratoire nto cyangwa ibikoresho byo murugo kugirango bitange ingufu nziza.
Abagenzuzi ba DC: Ukurikije imikorere yimiyoboro ihindura, abagenzuzi ba DC bakunze kugabanywamo ibyiciro bibiri: ububiko noguhindura.Guhindura ibiyobora bikosora, koroshya uruziga rufite ubwoko bwa capacitor yinjiza hamwe na choke coil yinjiza ubwoko bubiri, bigomba guhinduka ukurikije uburyo bwo guhinduranya inzira yo gukoresha.Ubwoko bwa choke coil bwinjira bukoreshwa muburyo bwo guhinduranya intambwe, mugihe ubwoko bwa capacitor bwinjiza bukoreshwa muburyo bwo guhinduranya ibintu.
Ibicuruzwa nibihinduka-hasi.
