The MPQ4590 is a primary-side regulator that provides accurate constant voltage (CV) regulation without an optocoupler. The MPQ4590 supports buck, buck-boost, boost, and flyback topologies and has an integrated 640V MOSFET to simplify structure and reduce costs. These features make the MPQ4590 an ideal regulator for low-power applications, such as home appliances and standby power. The MPQ4590 is a green-mode operation regulator. Both the peak current and switching frequency decrease as the load decreases. This feature provides excellent efficiency at light load and improves the overall average efficiency. Full protection features include thermal shutdown (OTP), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop protection. The MPQ4590 is available in a SOIC-8 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.
MPQ4590GS 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 MPQ4590GS datasheet above.
Electronic component spot-market pricing for MPQ4590GS 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 MPQ4590GS 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.
