TLHALOSO
MPQ8633A ke converter ea buck e kopantsoeng ka botlalo, e phahameng ea maqhubu, e lumellanang.E fana ka tharollo e kopaneng haholo ea ho fihlela tlhahiso ea 12A ho feta mefuta e mengata ea phepelo e pharalletseng e nang le taolo e ntle haholo ea mojaro le mela.MPQ8633A e sebetsa ka katleho e phahameng ho feta mefuta e mengata ea hona joale ea mojaro.
MPQ8633A e amohela mokhoa oa taolo o lefshoang ka hare ho nako (COT) o fanang ka karabelo ea nakoana e potlakileng le e nolofatsang botsitso ba loop.
Maqhubu a ts'ebetso a behiloe habonolo ho 600kHz, 800kHz, kapa 1000kHz ka tlhophiso ea MODE, e lumellang maqhubu a MPQ8633A hore a lule a sa fetohe ho sa tsotellehe matla a ho kenya / ho tsoa.
Mokhoa oa ho qala motlakase o hlahisoang o laoloa ke sebali sa ka hare sa 1ms.E ka eketsoa ka ho eketsa capacitor ho TRK/REF.Letšoao la Open-drain power good(PGOOD) le bonts'a tlhahiso e ka har'a sebaka sa eona sa motlakase.PGOOD e tlameletsoe ho pota 0.7V ka motlakase oa ho hula ka ntle ha phepelo e kenang e hlōleha ho matlafatsa MPQ8633A.
Likarolo tsa ts'ireletso tse kenyellelitsoeng ka botlalo li kenyelletsa ts'ireletso ea overcurrent (OCP), over-voltage protection (OVP), under-voltage protection (UVP), le overcurrent protection (OTP).
MPQ8633A e hloka palo e fokolang ea likarolo tse fumanehang habonolo, tse tloaelehileng, tsa ka ntle 'me e fumaneha ka har'a sephutheloana sa QFN 3mm x 4mm.
