The MP5403 is a monolithic power management unit containing two high-efficiency, step-down, switching converters and a load switch. The two regulators supply current up to 3.5A and 2.5A separately, and the load switch supplies up to 3A of load current with an extremely low RDS(ON). With an input range of up to 6V, the MP5403 is ideal for powering ASIC and SOC for solid-state drives and other compact power systems.The peak-current-mode control scheme with pulse-skip-mode operation provides the two switchers with fast transient response, high light-load efficiency, and minimum capacitance by using an interleaving PWM clock between the two switchers. The 3A load switch with a low 20mΩ on resistance provides flexible system configuration.A full set of enable control pins and power good open-drain indicators allow for easy implementation of the start-up and shutdown sequences. Full protection features include over-current protection (OCP) and thermal shutdown. The MP5403 requires a minimal number of readily available, standard, external components and is available in a small UTQFN-20 (2.5mmx3mm) package.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MP5403GQBU-Z is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MP5403GQBU-Z datasheet above.
Electronic component spot-market pricing for MP5403GQBU-Z fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for MP5403GQBU-Z depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
