1.
I-TPS54560B yi-60V, i-5A buck regulator ene-MOSFET ehlangeneyo ephezulu.Ulawulo lwemowudi yangoku lubonelela ngembuyekezo elula yangaphandle kunye nokukhethwa kwecandelo eliguquguqukayo.Imowudi esezantsi yokutsiba kwepulse yehlisa unikezelo olungalayishwanga lwangoku ukuya kwi-146µA.Xa i-EN (yenza) iphini itsalwa phantsi, ukucinywa konikezelo lwangoku kuyancitshiswa ukuya kwi-2µA.
I-Undervoltage blocking ibekwe ngaphakathi kwi-4.3V kodwa inokunyuswa kunye ne-EN (enable) pin.Irempu yokuqalisa i-voltage ephumayo inokulawulwa ngaphakathi ukuze ikwazi ukulawula inkqubo yokuqalisa elawulwayo kunye nokuphelisa ukudubula okugqithisileyo.
Uluhlu olubanzi lokutshintsha okuphindaphindiweyo luvumela ukulungiswa kokusebenza kakuhle okanye ubungakanani becandelo langaphandle.Imveliso yangoku yi-current cycle-by-cycle current.Ukuphindaphinda okuphindaphindiweyo kunye nokuvalwa kwe-thermal kukhusela amacandelo angaphakathi nangaphandle phantsi kweemeko zokugcwala.
I-TPS54560B iyafumaneka kwi-8-pin eyomelezwe thermally iphakheji ye-HSOIC PowerPAD.

I-DC-DC sisishunqulelo sesiNgesi somsinga othe ngqo ukuya ngqo ngoku, ngoko ke isekethe ye-DC-DC yisekethe apho umbane othile we-DC uguqulwa ube yixabiso lombane elahlukileyo.iisekethe ezisisiseko ze-DC-DC converter yi-converter ye-step-up, i-converter ye-step-down, kunye ne-step-up/down converter.Kwisekethe efanayo, kuya kubakho imisebenzi efana ne-step-up reverse kunye ne-step-down boost ngaxeshanye.

Iisekethe ze-DC-DC zihlelwa ngokomsebenzi.
I-Boost converters: Iisekethe eziguqula umbane ophantsi ukuya kumandla aphezulu.
Iziguquli zeBuck: Iisekethe eziguqula amandla ombane aphezulu ukuya kumbane ophantsi.
Ii-Inverters: Iisekethe ezitshintsha i-polarity ye-voltage, kukho iindidi ezimbini zeesekethe: i-positive ukuya kwi-negative kunye ne-negative ukuya kwi-positive.

I-transformer esezantsi ibhekisa kwicala legalelo lombane ophezulu, oguqulelwe kwisiphumo sombane ophantsi ofanelekileyo, ukuze ufezekise injongo yesiguquli sokuhla.I-transformer ye-step-down yinto ebaluleke kakhulu yesixhobo kwi-transmission and transformation system, kunye nokusebenza kwayo okuqhelekileyo akuhambelani kuphela nokhuseleko lwayo, kunye nonikezelo lwamandla oluthembekileyo lomsebenzisi, kodwa luchaphazela ngokuthe ngqo ukuzinza kwenkqubo yamandla.Ukucwangciswa kokukhusela i-step-down transformer kufuneka kuhlangane kuyo nayiphi na imeko, ayikwazi ukutshisa i-transformer, ukwenzela ukuba ingozi yande, echaphazela ukuzinza kwenkqubo yamandla.Ngaba umgaqo wokungeniswa kwe-electromagnetic induction, ngoku inqanaba elinye eliphinda-phinda kabini i-transformer njengomzekelo wokuchaza umgaqo wayo osisiseko wokusebenza: xa icala eliphambili le-winging kunye ne-voltage, ukuqukuqela kwangoku kumbindi kuya kuvelisa ukuguquguquka okutshintshileyo oku kubizwa ngokuba yeyona nto iphambili. i-flux, i-flux ephambili iya kudlula, i-primary, i-second winding, i-winding iya kuvelisa amandla e-electromotive induction, ngoko ukuba ukufikelela kwecala lesibini kumthwalo, kuya kubakho ukuhamba kwangoku, ukuvelisa umbane.
