Product Details
Key Features

The MP5403B is a monolithic power management unit containing two high-efficiency, step-down, switching converters and a load switch. The two regulators supply peak currents up to 5A and 4A 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 MP5403B is ideal for powering ASIC and SOC for solid-state drives (SSD) 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 a minimal number of capacitors 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 MP5403B requires a minimal number of readily available, standard, external components and is available in a small UTQFN-20 (2.5mmx3mm) package.

YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is MP5403BGQBU-P, and what package does it use?

MP5403BGQBU-P 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 MP5403BGQBU-P datasheet above.

Why is pricing for MP5403BGQBU-P available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for MP5403BGQBU-P 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.

How quickly can MP5403BGQBU-P be shipped once quoted?

Lead times for MP5403BGQBU-P 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.
