♠ TPS54302 4.5-V to 28-V Input, 3-A Output, EMI-Friendly Synchronous Step-down Beddelka
Aaladda TPS54302 waa 4.5-V ilaa 28-V kala duwanaanta korantada, 3-A isku beddelka buck-ka.Qalabku waxa ku jira laba FETs oo isku dhafan, loop gudaha ahmagdhow, iyo 5-ms jilicsan oo gudaha ah ayaa bilaabmaya si loo yareeyo tirada qaybaha.
Marka la isku daro MOSFET-yada oo la shaqaaleysiiyo xirmada SOT-23, aaladda TPS54302 waxa ay gaartaa cufnaanta awoodda sare waxayna ku siinaysaa raad yar oo PCB ah.
Hirgelinta qaab-dhismeedka sare ee Eco-ku waxay kordhisaa waxtarka culeyska fudud waxayna yaraynaysaa khasaaraha korontada.
Qalabka TPS54302, hawlgalka fidinta soo noqnoqda ayaa loo soo bandhigay dhimista EMI.
Xadka hadda socda ee-wareegga-wareegga ah ee MOSFET-ta-sare waxay ilaalisaa beddelaha xaalad culeys xad dhaaf ah waxaana lagu xoojiyey MOSFET-dhinac-hooseeya xadka hadda socda kaasoo ka hortagaya cararka hadda socda.Ka ilaalinta qaabka hiccup waxa ay kicisaa haddii xaalada xad dhaafka ahi ay sii jirto wax ka badan wakhtigan xaadirka ah.
