♠ TPS54302 4.5-V mpaka 28-V Zolowetsa, 3-A Output, EMI-Friendly Synchronous Step-Down Converter
Chipangizo cha TPS54302 ndi 4.5-V mpaka 28-V yolowetsa magetsi, 3-A synchronous buck converter.Chipangizocho chimaphatikizapo ma FET awiri osakanikirana osakanikirana, loop yamkatichipukuta misozi, ndi 5-ms mkati mofewa kuyamba kuchepetsa chiwerengero cha zigawo.
Mwa kuphatikiza ma MOSFET ndikugwiritsa ntchito phukusi la SOT-23, chipangizo cha TPS54302 chimakwaniritsa kachulukidwe kamphamvu kwambiri ndipo chimapereka gawo laling'ono pa PCB.
Kukhazikitsa kwapamwamba kwa Eco-mode kumakulitsa mphamvu yopepuka komanso kumachepetsa kutayika kwa magetsi.
Mu chipangizo cha TPS54302, ntchito yafupipafupi yofalitsa sipekitiramu imayambitsidwa pofuna kuchepetsa EMI.
Malire aposachedwa a MOSFET amtundu uliwonse amateteza chosinthiracho kuti chikhale chodzaza kwambiri ndipo chimakulitsidwa ndi malire apano a MOSFET aulere omwe amalepheretsa kuthawa komwe kulipo.Chitetezo chamtundu wa hiccup chimayambika ngati vuto la overcurrent likupitilira kwa nthawi yayitali kuposa pano.
