TPS62202DBVR - Integrated Circuits (ICs), Power Management (PMIC), Voltage Regulators - DC DC Switching Regulators

Iyo yakajairwa switch-capacitor inoshandura ine mahombe mana eMOS switch ane yakajairwa yekuchinja kutevedzana kwekuchinja, kupeta kana kudzika nepakati magetsi ekuisa.Kuendesa uye kuchengetedza kwesimba kunopihwa nevekunze capacitors, iyo kambani yakataurwa neChina yekuzviparadzanisa inoshandura zvigadzirwa munzvimbo yemusika, kugadzira uye kushanda, kunze kwechigadzirwa uye kunze kwenyika, indasitiri yekudyara nharaunda uye kusimudzira kwakasimba kwenyika yedu pahwaro hweiyi indasitiri yekusimudzira. maitiro ekuita musanganiswa wehutano uye huwandu hwekuongorora uye kufanotaura.Yakabatanidzwa mumashanduri, magetsi ekudzora, maregulator uye zvimwe zvakaderera-voltage zvinotsigira zvigadzirwa kugadzirwa, kutsvagisa nekusimudzira, kutengesa, "kutevedzera hunyanzvi hwemakambani, zvigadzirwa zvikuru ndezvi: SBW yakakwirira-simba inodzoreredza simba regulator, SBW-F sub-inodzorwa simba regulator. , SVC yakakwirira-chaiyo otomatiki AC regulator, precision yekuchenesa regulator, microcomputer isiri-contact regulator, SG \ SBK isolation transformer, OSG\QZB autotransformer, ZSG\ZDG rectifier transformer, SSG servo transformer, DN kuramba welding mvura-yakatonhorera transformer, reactor, Bata autotransformer, column-type high-power electric regulator uye mamwe maseti akazara emidziyo yemagetsi.Zvigadzirwa zvine dhizaini nyowani, vhoriyamu diki, chimiro chakanaka, kurasikirwa kwakaderera, ruzha, kupikisa uye zvimwe zvakanakira. Inoshandiswa zvakanyanya mumaindasitiri nemabhizinesi emigodhi , machira emuchina, kudhinda uye kurongedza, petrochemical indasitiri, zvikoro, zvitoro, zvinokwirisa, post uye nharembozha, michina yekurapa uye dzimwe nguva dzese dzinoda zvakajairwa voltage assurance.

Munguva yechikamu chekutanga chekuchinja kwekuchinja, magetsi ekupinza anoshandiswa kune capacitor (C1).Muchikamu chechipiri chekushandura, mutero unotamiswa kubva kuC1 kusvika kune yechipiri capacitor C2.Iyo yakajairika yekuvakwa kweiyo switched-capacitor converter inoshandura inoshandura, uko C2 ine yakavakirwa yakanaka terminal uye yayo yakaipa terminal inopfuura yakashata yakabuda voltage.Mushure memazuva mashomanana, magetsi kuburikidza neC2 inoshandiswa kune magetsi ekuisa.Tichifunga kuti hapana mutoro paC2, hapana kurasikirwa muchinja uye hapana kuramba kupikisa mu capacitor, iyo inobuda voltage ichava chaiyo yakaipa yemagetsi ekupinza.Muchokwadi, kushanda kweiyo dhizaini yekufambisa (uye nekudaro iko kurongeka kweiyo inobuda voltage) kunoenderana nekuchinja frequency, kushorwa kweiyo switch, kukosha kwecapacitor uye kuramba kuramba.Iyo yakafanana topology yakapetwa kaviri inoshandisa imwechete switch uye capacitor bhangi, asi inoshandura yekubatanidza yepasi uye yekuisa voltage.Mamwe mavhezheni akaomarara anoshandisa mamwe ma switch uye ma capacitor kuti awane mamwe mareshiyo eshanduko yekuisa kune inobuda voltage uye, mune dzimwe nguva, yakasarudzika switching sequence kugadzira hukama hwepakati.Mune yavo yakapusa chimiro, switched capacitor converters haisi voltage inodzorwa.Mamwe matsva eNational Semiconductor switched-capacitor converters ane otomatiki anogadzirika kuwana mazinga kuti abudise inodzorwa kubuda;mamwe ma switched-capacitor anoshandura anoshandisa yemukati yakaderera yekudonha mutsara regulator kuburitsa isina kudzorwa.
