♠ 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-by-wareegga ee MOSFET-ta sare waxay ka 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.
