♠ 4.5V ukuya ku-18V INPUT, 2-A ISIGUNGU ESIVUMELANISAYO ISINYATHELO ESENTSHA ESINE-FET EHLANGANISIWE
I-TPS54229 iyi-adaptive on-time D-CAP2™ mode synchronous buck converter. I-TheTPS54229 inika amandla abaklami bohlelo ukuthi baqedele izilawuli zamabhasi zamandla emishini yokuphela kweqanda ene-ovarious nge-acost ephumelelayo, isibalo sengxenye ephansi, isisombululo samanje esibekwe eceleni. Iluphu yokulawula eyinhloko ye-TPS54229 isebenzisa isilawuli semodi ye-D-CAP2™ esinikeza impendulo yesikhashana esheshayo engenazo izingxenye zesinxephezelo zangaphandle. I-TPS54229 futhi inomjikelezo wobunikazi ovumela idivayisi ukuthi ikwazi ukusebenzisa kokubili ama-capacitor okukhiphayo alinganayo ochungechunge (ESR), afana ne-POSCAP noma i-SP-CAP, kanye nama-ceramic capacitor e-ESR aphansi kakhulu. Idivayisi isebenza kusuka ku-4.5-V kuya ku-18-V VIN okokufaka. I-voltage ephumayo ingahlelwa phakathi kuka-0.76 V no-7 V. Idivayisi iphinde ibe nesikhathi sokuqala esithambile esilungisekayo. I-TPS54229 iyatholakala kuphakeji ye-8-pin DDA, futhi iklanyelwe ukusebenza ukusuka -40°C kuya ku-85°C.
