I-TPS53511 yimowudi ye-D-CAP2™ eguqukayo ye-synchronous buck converter.Isixhobo sifanelekile kumanqaku omthwalo (i-POL) kwiinkqubo zamandla ekhompyutheni, kwaye ibonelela ngexabiso elisebenzayo, ukubalwa kwecandelo eliphantsi, isisombululo esisezantsi sokulinda.I-loop yolawulo ephambili ye-TPS53511 isebenzisa ulawulo lwemowudi ye-DCAP2™ ukubonelela ngempendulo yexeshana ekhawulezayo engenazo izinto zangaphandle.Ukulawulwa kwexesha elisebenzayo lixhasa ukusebenza okungenamthungo phakathi kwemodi ye-PWM ngexesha leemeko zomthwalo onzima kunye nokunciphisa ukusebenza rhoqo ngexesha leemeko zomthwalo wokukhanya ekusebenzeni okuphezulu.
I-TPS53511 ibandakanya isekethe yobunikazi eyenza ukuba isixhobo silungelelanise kuzo zombini ii-capacitors ezisezantsi ezilinganayo (ESR) zemveliso, njengePOSCAP okanye i-SP-CAP, kunye ne-ultra-low ESR capacitors ceramic.Isixhobo sisebenza ukusuka kwi-4.5-V ukuya kwi-18-V igalelo lokubonelela, kwaye ukusuka kwi-2-V ukuya kwi-18-V igalelo lombane wokufaka amandla.Isixhobo sinexesha elicothayo elinohlengahlengiso lokuqalisa kunye nokusebenza kakuhle kwamandla.Ikwaxhasa ukuqala okuthambileyo kwangaphambili.I-TPS53511 ifumaneka kwiphakheji ye-16-pin ye-QFN, kwaye yenzelwe ukusebenza ukusuka ku--40 ° C ukuya kuma-85 ° C.
