♠ Okokufaka okungu-4.5-V kuya ku-18-V, 1.5-A Isilawuli Esisuka Phansi Esine-Integrated Switcher
I-TPS53511 iyi-adaptive on-time D-CAP2™ mode synchronous buck converter. Idivayisi ifanele amaphuzu okulayisha (i-POL) kumasistimu wamandla ekhompuyutha, futhi inikeza inani elingabizi kakhulu, isibalo sengxenye ephansi, isisombululo samanje sokulinda esiphansi. Iluphu yokulawula eyinhloko ye-TPS53511 isebenzisa isilawuli semodi ye-DCAP2™ ukuze inikeze impendulo yesikhashana esheshayo engenazo izingxenye zangaphandle. Ukulawulwa kwesikhathi okuguquguqukayo kusekela ukusebenza okungenamthungo phakathi kwemodi ye-PWM phakathi nezimo zomthwalo osindayo kanye nokusebenza okuncishisiwe kwemvamisa phakathi nezimo zokulayisha ukukhanya ukuze usebenze kahle kakhulu.
I-TPS53511 ihlanganisa umjikelezo wobunikazi ovumela idivayisi ukuthi ikwazi ukuzivumelanisa nawo womabili ama-capacitor okukhiphayo alinganayo ochungechunge (ESR), afana ne-POSCAP noma i-SP-CAP, kanye nama-ceramic capacitor e-ESR aphansi kakhulu. Idivayisi isebenza ukusuka ku-4.5-V ukuya ku-18-V wokufakwayo kokunikezwayo, futhi kusukela ku-2-V kuya ku-18-V okufakwayo kwamandla kagesi wokufaka amandla. Idivayisi inesikhathi sokuqalisa kancane esilungisekayo kanye nomsebenzi omuhle wamandla. Iphinde isekele isiqalo esithambile esenziwe ngaphambili. I-TPS53511 itholakala ngephakeji ye-QFN engu-16-pin, futhi yakhelwe ukusebenza ukusuka ku--40°C kuya ku-85°C.
