MP8774H Synchronous Mohato-Down Converter

MPS 'MP8774H e sebetsa khafetsa ka nako (COT) mme e fana ka karabelo e potlakileng haholo, moralo o bonolo oa loop, le taolo e thata haholo ea tlhahiso

MPS's MP8774H Synchronous Step-Down Converter MPS 'MP8774H ke sesebelisoa se kopaneng ka botlalo, se nang le maqhubu a phahameng, se lumellanang, se lokisitsoeng, se theohelang fatše, se fetolelang ka mokhoa o nang le matla a ka hare a MOSFET. Sesebelisoa sena se fihlela 12 A ea tlhahiso e sa khaotseng e nang le mojaro o motle haholo le taolo ea mohala ho palo e pharaletseng ea ho kenya ho tloha 3 V ho isa 18 V. MP8774H e sebelisa ts'ebetso ea li-synchronous mode bakeng sa ts'ebetso e phahameng ho feta palo ea hona joale ea mojaro. Likarolo tsa ts'ireletso e felletseng li kenyelletsa tšireletso ea nakoana (SCP), ts'ireletso e fetelletseng (OCP), ts'ireletso ea undervoltage (UVP) le ho koala mocheso. Ts'ebetso ea taolo ea COT e fana ka karabelo e potlakileng haholo, moralo o bonolo oa loop, le taolo e thata haholo ea tlhahiso. MP8774H e fumaneha ka sephutheloana sa QFN-16 (3 mm x 3 mm).
