♠ TPS54302 4.5-V ho 28-V Input, 3-A Output, EMI-Friendly Synchronous Step-Down Converter
Sesebelisoa sa TPS54302 ke 4.5-V ho isa ho 28-V ea ho kenya motlakase, 3-A synchronous buck converter. Sesebelisoa se kenyelletsa li-FET tse peli tse kopantsoeng, loop e ka harematšeliso, le 5-ms ka hare bonolo qala ho fokotsa palo ea likarolo.
Ka ho kopanya li-MOSFET le ho sebelisa sephutheloana sa SOT-23, sesebelisoa sa TPS54302 se fihlella matla a phahameng a matla mme se fana ka sebaka se senyenyane ho PCB.
Ts'ebetso e tsoetseng pele ea Eco-mode e eketsa katleho ea mojaro o bobebe mme e fokotsa tahlehelo ea matla.
Ka sesebelisoa sa TPS54302, ts'ebetso ea "frequency spread spectrum" e hlahisoa bakeng sa phokotso ea EMI.
Moeli oa hona joale oa cycl-by-cycle ho MOSFET ea mahlakoreng a mabeli e sireletsa converter boemong bo boima haholo 'me e matlafatsoa ke moeli oa hona joale oa MOSFET oa freewheeling o thibelang ho baleha hona joale. Tšireletso ea mokhoa oa Hiccup e hlahisoa haeba boemo ba overcurrent bo ntse bo tsoela pele nako e telele ho feta nako ea hona joale.
