TPS53511 ke sesebelisoa sa ho fetolela se sebetsang ka nako sa D-CAP2™ se lumellanang le buck. Sesebelisoa se loketse lintlha tsa mojaro (POL) lits'ebetsong tsa matla a khomphutha, 'me se fana ka palo e theko e tlaase, e tlase ea likarolo, tharollo ea hajoale ea boemo bo tlase. Loop ea mantlha ea taolo bakeng sa TPS53511 e sebelisa taolo ea mokhoa oa DCAP2™ ho fana ka karabelo ea nakoana e se nang likarolo tsa kantle. Taolo e sebetsang ka nako e ts'ehetsa ts'ebetso e se nang moeli pakeng tsa mokhoa oa PWM nakong ea maemo a boima bo boima le ho fokotsa ts'ebetso ea makhetlo a mangata nakong ea maemo a boima bo bobebe bakeng sa ts'ebetso e phahameng.
TPS53511 e kenyelletsa potoloho ea thepa e nolofalletsang sesebelisoa ho ikamahanya le li-capacitor tse tsoang ka tlase tse lekanang (ESR), joalo ka POSCAP kapa SP-CAP, le li-ultra-low ESR ceramic capacitor. Sesebelisoa se sebetsa ho tloha ho 4.5-V ho ea ho 18-V ho kenya letsoho, le ho tloha ho 2-V ho ea ho 18-V ho kenya motlakase oa motlakase. Sesebelisoa se na le nako e ka feto-fetohang ea ho qala butle le ts'ebetso e ntle ea matla. E boetse e tšehetsa prebiased soft start. TPS53511 e fumaneha ka har'a sephutheloana sa 16-pin QFN, 'me e etselitsoe ho sebetsa ho tloha ho -40°C ho isa ho 85°C.
