MP8774H Synchronous Gawo-Low Converter

MPS 'MP8774H imagwira ntchito mosalekeza pa nthawi (COT) ndipo imapereka yankho mwachangu kwambiri, kapangidwe kosavuta, komanso malamulo olimba kwambiri

MPS's MP8774H Synchronous Step-Down Converter MPS 'MP8774H ndi yophatikiza kwathunthu, kuthamanga kwambiri, kulumikizana, kukonzedwa, kutsika, chosinthira chosinthira ndi mphamvu zamkati za MOSFET. Chida ichi chimakwaniritsa 12 A yazopitilira zomwe zilipo pakadali pano zokhala ndi katundu wabwino kwambiri komanso mzere wama line pamitundu ingapo yoyambira 3 V mpaka 18 V. MP8774H imagwiritsa ntchito njira yolumikizirana kuti ichite bwino kuposa kuchuluka kwaposachedwa. Zida zonse zodzitchinjiriza zimaphatikizapo chitetezo chakanthawi kochepa (SCP), chitetezo chapamwamba (OCP), chitetezo chotsikira (UVP), ndi kuzimitsa matenthedwe. Ntchito yoyang'anira COT imapereka yankho lachangu kwambiri, mayendedwe osavuta, komanso malamulo olimba kwambiri. MP8774H imapezeka mu phukusi la QFN-16 (3 mm x 3 mm).
