1.
I-TPS54560B iyi-60V, 5A buck regulator ene-MOSFET ephezulu ehlangene.Ukulawula imodi yamanje kunikeza isinxephezelo esilula sangaphandle kanye nokukhetha kwengxenye eguquguqukayo.Imodi ephansi ye-ripple pulse jump yehlisa ukunikezwa okungalayishiwe okwamanje ku-146µA.Uma iphinikhodi ye-EN (vumela) idonswa phansi, amandla okunikezwayo okuvala shaqa ancishiswa abe ngu-2µA.
I-Undervoltage blocking isethwe ngaphakathi ukuze ibe ngu-4.3V kodwa inganyuswa ngephinikhodi ethi EN (enable).Irempu yokuqalisa i-voltage ephumayo ingalawulwa ngaphakathi ukuze ivumele inqubo yokuqalisa elawulwayo futhi iqede ukudubuleka ngokweqile.
Ububanzi befrikhwensi yokushintsha okubanzi buvumela ukwenziwa kahle kokusebenza kahle noma usayizi wengxenye yangaphandle.Okuphumayo okwamanje okulinganiselwe komjikelezo nomjikelezo.Ukugoqa imvamisa nokuvalwa kwe-thermal kuvikela izingxenye zangaphakathi nezangaphandle ngaphansi kwezimo zokugcwala kakhulu.
I-TPS54560B iyatholakala ngephakeji ye-HSOIC PowerPAD enamaphini ayi-8.

I-DC-DC isifinyezo sesiNgisi se-direct current kuya ku-direct current, ngakho-ke isekethe ye-DC-DC iyisekhethi lapho ukunikezwa kwamandla kwe-DC okuthile kuguqulwa kube ivelu ye-voltage ehlukile.amasekhethi ayisisekelo esiguquli se-DC-DC ayisiguquli esikhuphukayo, isiguquli esisuka phansi, kanye nesiguquli sokukhuphuka/phansi.Kusekhethi efanayo, kuzoba nemisebenzi efana nokuhlehla kwesinyathelo-up kanye nokwehliswa kwezinyathelo ngasikhathi sinye.
3.
Amasekhethi e-DC-DC ahlukaniswa ngomsebenzi.
I-Boost converters: Izifunda eziguqula ama-voltage aphansi abe ama-voltage aphezulu.
Iziguquli ze-Buck: Izifunda eziguqula ama-voltage aphezulu abe ama-voltage aphansi.
Ama-Inverters: Izifunda ezishintsha i-polarity ye-voltage, kunezinhlobo ezimbili zamasekhethi: positive ukuya ku-negative kanye negative kuya kokuphozithivu.

I-transformer eyehlayo iwukubhekisa ohlangothini lokufakwayo lwe-voltage ephezulu, eguqulelwe ku-voltage esezingeni eliphansi uma kuqhathaniswa, ukuze kufezwe injongo yesiguquli esisuka phansi.I-transformer eyehlayo iyingcezu yemishini ebaluleke kakhulu ohlelweni lokudlulisa nokuguqula, futhi ukusebenza kwayo okuvamile akuhlobene nje nokuphepha kwayo kuphela, kanye nokunikezwa kwamandla okuthembekile komsebenzisi, kodwa futhi kuthinta ngokuqondile ukuzinza kwesistimu yamandla.Ukumiswa kokuvikelwa kwe-step-down transformer kufanele kuhlangane kunoma yikuphi, akukwazi ukushisa i-transformer, ukuze ingozi ikhule, ithinte ukuzinza kwesistimu yamandla.Ingabe isimiso sokungeniswa kwe-electromagnetic, manje isiguquli esinamawindi aphindwe kabili esinesigaba esisodwa njengesibonelo sokuchaza isimiso saso esiyisisekelo sokusebenza: lapho uhlangothi oluyinhloko lwe-voltage evunguzayo kanye ne-voltage, amandla agelezayo emnyombo azokhiqiza ukuguquguquka okushintshwayo lokhu kugeleza kubizwa ngokuthi okuyinhloko. i-flux, i-flux eyinhloko izodlula, okuyisisekelo, ukujika kwesibili, ukuvuthwa kuzokhiqiza amandla e-electromotive induction, khona-ke uma uhlangothi lwesibili lufinyelela umthwalo, kuzoba nokugeleza kwamanje, ukukhiqiza ugesi.
