The MPM3686 is an easy-to-use fully integrated 20A step-down DC/DC power module. It integrates the DC/DC converter, power inductor, input/output capacitors and the necessary resistors/capacitors in a compact QFN 12mmX15mmX4mm package. This total power solution needs as few as two external components (one resistor and one capacitor) to work. MPM3686 can deliver 20A output current over a wide input supply voltage range with excellent load and line regulation. The MPM3686 uses Constant-On-Time (COT) control to provide fast transient response and ease the loop stabilization. The default under voltage lockout threshold is internally set around 4.1V, but a resistor network on the enable pin can increase this threshold. The MPM3686 has an internal LDO to power the control circuits and the integrated power devices. This LDO can be disabled by an external 5V to boost the efficiency. The MPM3686 has an internal about 3ms soft start (SS) timer. It can be increased with an extra SS capacitor. An open drain power good signal indicates that the output voltage is within nominal voltage range. The MPM3686 has fully integrated protection features that include over-current protection, over-voltage protection and thermal shutdown.
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.
MPM3686 is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Unclassified. 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 MPM3686 datasheet above.
Electronic component spot-market pricing for MPM3686 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 MPM3686 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.
