♠ I-4.5V ukuya kwi-18V INPUT, 2-INYATHELO ELIVUMELANISAYO ESENTSHA I-CONVERTER NE-FET EHLANGANISIWEYO
I-TPS54229 yimowudi ye-D-CAP2™ eguqukayo ye-synchronous buck converter. I-TPS54229 yenza abaqulunqi benkqubo bagqibezele izilawuli zebhasi zamandla zesixhobo esine-ovarious ngexabiso elisebenzayo, ukubalwa kwecandelo eliphantsi, isisombululo sangoku esisezantsi. Ilophu yolawulo ephambili ye-TPS54229 isebenzisa ulawulo lwemowudi ye-D-CAP2™ ebonelela ngempendulo yexeshana ekhawulezayo engenazo izinto zembuyekezo zangaphandle. I-TPS54229 ikwanayo nesekethe yobunikazi eyenza ukuba isixhobo sithathelwe 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 leVIN. I-voltage ephumayo inokucwangciswa phakathi kwe-0.76 V kunye ne-7 V. Isixhobo sikwabonisa ixesha lokuqalisa elithambileyo elihlengahlengiswayo. I-TPS54229 iyafumaneka kwi-8-pin DDA package, kwaye yenzelwe ukusebenza ukusuka ku-40°C ukuya kuma-85°C.
