Semicon Itsva uye Yekutanga IC Chip Distributor Inopisa Inopa ICS Electronic Zvikamu TPS54560BDDAR

1.

Iyo TPS54560B ndeye 60V, 5A buck regulator ine yakabatanidzwa yakakwirira-parutivi MOSFET.Yazvino modhi yekudzora inopa nyore muripo wekunze uye inoshanduka yechikamu sarudzo.Iyo yakaderera ripple pulse jump mode inoderedza iyo isina kurodherwa yezvino ku 146µA.Kana iyo EN (gonesa) pini yakadhonzwa yakadzikira, iyo yekuvharisa yekugovera ikozvino inoderedzwa kusvika 2µA.

Iyo Undervoltage blocking inoiswa mukati kusvika 4.3V asi inogona kuwedzerwa ne EN (enable) pini.Iyo inobuda voltage yekutanga-up ramp inogona kudzorwa mukati kuti igone kudzorwa kutanga-up maitiro uye kubvisa overshoot.

Iyo yakakura switching frequency renji inobvumira optimization yekubudirira kana yekunze chikamu saizi.Ikozvino yakabuda ishoma kutenderera-ne-kutenderera ikozvino.Frequency foldback uye thermal shutdown inodzivirira zvinhu zvemukati nekunze pasi pemamiriro ekuremedza.

Iyo TPS54560B inowanikwa mune 8-pini yakawedzera kupisa HSOIC PowerPAD package.

DC-DC ndiyo chidimbu cheChirungu chekuti direct current to direct current, saka DC-DC circuit idunhu umo imwe DC magetsi inoshandurwa kuita imwe voltage value.iwo maseketi ekutanga eDC-DC inoshandura inhanho-kumusoro inoshandura, nhanho-pasi inoshandura, uye nhanho-kumusoro/pasi inoshandura.Mudunhu rimwe chete, pachava nemabasa akadai senge nhanho-kumusoro reverse uye nhanho-pasi inosimudzira panguva imwe chete.

Maseketi eDC-DC anokamurwa nebasa.

Boost converters: Maseturu anoshandura yakaderera voltages kune yakakwira voltages.

Buck converters: Masekete anoshandura akakwira voltages kune yakaderera voltages.

Inverters: Masekete anoshandura polarity yemagetsi, kune marudzi maviri emaseketi: akanaka kune asina kunaka uye asina kunaka kune akanaka.

A nhanho-pasi transformer ndeyekureva kudivi rekupinza reiyo yakakwira voltage, inoshandurwa kune inobuda yakaderera yakanakira voltage, kuitira kuti izadzise chinangwa chekutsika-pasi transformer.The nhanho-pasi transformer chinhu chakakosha zvikuru chidimbu chemidziyo mukufambisa uye kushandura hurongwa, uye kushanda kwayo kwakajairika hakusi kungoenderana nekuchengetedza kwayo, uye simba remushandisi rakavimbika, asi rinokanganisawo kugadzikana kwesimba remagetsi.Kugadziriswa kwechitsinho-pasi chekudzivirira chekushandura kunofanira kusangana chero ipi zvayo, haigoni kupisa transformer, kuitira kuti njodzi iwedzere, inokanganisa kugadzikana kwesimba remagetsi.Ndiyo musimboti we electromagnetic induction, ikozvino imwe-phase-double-winding transformer semuenzaniso kutsanangura yayo yekutanga kushanda musimboti: kana iyo yekutanga divi remhepo inofefetera pamwe nevoltage, inoyerera ikozvino mukatikati inoburitsa inochinja inoyerera iyi flux inonzi iyo huru. flux, iyo huru inoyerera ichapfuura nepakati, yepuraimari, yechipiri mhepo, iyo inomonereka ichaburitsa induction electromotive simba, zvino kana yechipiri rutivi rwekupinda kumutoro, pachave nekuyerera kwazvino, kugadzira magetsi.
