Product Details
Key Features

The MPQ8643 is a fully integrated, high-frequency, synchronous step-down converter. It offers a very compact solution that can achieve up to 20A of output current (IOUT) across a wide input voltage (VIN) range, with excellent load and line regulation. The MPQ8643 operates at high efficiency across a wide IOUT load range. Internally compensated constant-on-time (COT) control provides fast transient response and eases loop stabilization. The selectable switching frequency (fSW) can be set to 600kHz, 800kHz, or 1000kHz by configuring the MODE pin. This maintains a constant fSW, regardless of VIN and the output voltage (VOUT). During start-up, the internal soft-start timer (tSS) (1ms) ramps up VOUT in a controlled manner. tSS can be increased by adding a capacitor on the TRK/REF pin. An open-drain power good (PG) signal indicates whether VOUT is within its nominal voltage range. If the input fails to supply power to the MPQ8643, then the PG voltage (VPG) is clamped at about 0.7V via an external pull-up voltage. Fully integrated protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP). The MPQ8643 requires a minimal number of readily available, standard external components, and is available in a QFN-21 (3mmx4mm) 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 MPQ8643GLE-P, and what package does it use?

MPQ8643GLE-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 MPQ8643GLE-P datasheet above.

Why is dynamic quotation used instead of a fixed price for MPQ8643GLE-P?

Electronic component spot-market pricing for MPQ8643GLE-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.

What is the delivery timeline after placing an order for MPQ8643GLE-P?

Lead times for MPQ8643GLE-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.
