The MPQ2189 is a highly integrated, high-frequency, synchronous step-down converter with a serial interface. The MPQ2189 can support up to 4A of load current across an input voltage (VIN) supply range from 2.7V to 6V, with excellent load and line regulation. Constant-frequency hysteretic mode provides an extremely fast transient response without loop compensation to achieve high efficiency under light-load conditions. The output voltage (VOUT) can be controlled on the fly via a 3.4Mbps serial interface. The VOUT range can be adjusted from 0.6V to 1.235V in 5mV steps. The VOUT slew rate, switching frequency (fSW), and power-save mode can be configured via the serial interface. Full protection features include internal soft start (SS), over-current protection (OCP), and thermal shutdown. The MPQ2189 requires a minimal number of readily available, standard external components, and is available in a compact QFN-14 (2.5mmx3mm) 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.
MPQ2189GQBE-AEC1-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 MPQ2189GQBE-AEC1-P datasheet above.
Electronic component spot-market pricing for MPQ2189GQBE-AEC1-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.
Lead times for MPQ2189GQBE-AEC1-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.
