Teknik Özellikler
MPM3630GQV-Z is a fully integrated synchronous step-down DC-DC power module manufactured by MPS (Monolithic Power Systems). It integrates controller, power MOSFETs, power inductor and input/output capacitors into a single compact QFN package, eliminating most peripheral discrete components for ultra-simplified power designMPS。
