Product Details
Key Features

The MP3421 is a high-efficiency, synchronous, current–mode, step-up converter with true output disconnect.The MP3421 starts up from low input voltage (as low as 1.9V) while providing in-rush current limiting and output short-circuit protection. The integrated, P-channel synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode; the P-channel disconnects the output load from the input during shutdown. The MP3421 has 600kHz switching frequency, which accommodates small external components. In addition, its internal compensation and soft-start functions minimize external component count. The MP3421 provides a compact solution for a 5V output, 2.1A load requirement, using a supply voltage as low as 2.8V.The MP3421 is available in a 14-pin QFN 2mmx2mm 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.

  • 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 MP3421, and what package does it use?

MP3421 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 MP3421 datasheet above.

Why is pricing for MP3421 available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for MP3421 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 MP3421 be shipped once quoted?

Lead times for MP3421 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.
