Igenzura ry'umurongo

Muriibikoresho bya elegitoroniki, umurongo ugenzura ni aamashanyarazibikoreshwa mukubungabunga voltage ihamye.[1]Kurwanya ibiyobora biratandukana ukurikije ibyinjijwe byinjira hamwe numutwaro, bikavamo guhoraho kwa voltage.Umuzenguruko ugenzura uratandukanyekurwanywa, guhora uhindura aamashanyaraziumuyoboro kugirango ukomeze gusohora voltage ihoraho kandi uhore ukwirakwiza itandukaniro riri hagati yinjiza na voltage yagenzuwe nkukoubushyuhe.Ibinyuranye, aguhinduranyaikoresha igikoresho gikora gifungura no kuzimya (oscilates) kugirango ugumane impuzandengo y'ibisohoka.Kuberako voltage yagenzuwe kumurongo ugenzura igomba guhora munsi yumubyigano winjiza, imikorere iragabanuka kandi voltage yinjira igomba kuba ndende bihagije kugirango ihore yemerera igikoresho gikora kumanura voltage.

Abagenzuzi b'umurongo barashobora gushyira igikoresho kigenga ugereranije n'umutwaro (shuntumugenzuzi) cyangwa arashobora gushyira igikoresho kigenzura hagati yinkomoko nu mutwaro wagenzuwe (urukurikirane rukurikirana).Igenzura ryoroheje ryumurongo rishobora kuba ririmo bike nka aZener dioden'uruhererekane rw'uruhererekane;byinshi bigoye kugenzura harimo ibyiciro bitandukanye bya voltage yerekanwe, ikosa ryongera imbaraga hamwe nimbaraga zo gutambuka.Kuberako umurongoamashanyarazini ikintu gisanzwe cyibikoresho byinshi, umugenzuzi umwe-chipICni rusange.Abagenzuzi b'umurongo barashobora kandi kuba bagizwe n'inteko ya discret ikomeye-imiterere cyangwavacuum tubeIbigize.

Nubwo izina ryabo, abagenzuzi b'umurongo niimirongo idafite umurongokuberako zirimo ibice bitari umurongo (nka Zener diode, nkuko bigaragara hepfo muribyoroheje shunt) kandi kubera ko ibisohoka voltage bihoraho muburyo bwiza (kandi umuzenguruko ufite ibisohoka bihoraho bidashingiye kubyo winjije ni umurongo utari umurongo.)[2]

Ibisobanuro kuri TLV702

TLV702 yuruhererekane rwo hasi-yataye (LDO) umurongo ugenzura ni ibikoresho bituje bigezweho hamwe numurongo mwiza kandi wikoreza imikorere yinzibacyuho.Izi LDOs zagenewe imbaraga-zikoresha imbaraga.Igicucu cyuzuye hamwe na amplifier yibeshya itanga muri rusange 2%.Urusaku ruke rusohoka, igipimo kinini cyo gutanga amashanyarazi (PSRR), hamwe n’umuvuduko ukabije w’amashanyarazi bituma uruhererekane rwibikoresho rwiza muguhitamo kwinshi ibikoresho bikoreshwa na batiri.Ibikoresho byose verisiyo ifite ihagarikwa ryumuriro nigihe ntarengwa cyumutekano.

Byongeye kandi, ibyo bikoresho birahagaze neza hamwe nubushobozi bwiza bwo gusohora 0.1 µF gusa.Iyi mikorere ituma ikoreshwa rya capacator zihenze zifite imbaraga zo kubogama kwinshi hamwe nubushyuhe bukabije.Ibikoresho bigenga neza neza nta bisohoka umutwaro.

Urukurikirane rwa TLV702P rutanga kandi uruziga rukora kugirango rusohore vuba ibisubizo.

TLV702 ikurikirana ya LDO igenzura umurongo iraboneka muri SOT23-5 na 1.5-mm × 1.5-mm ya WSON-6.
