The MPQ4431 is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated, internal, high-side and low-side power MOSFETs. It provides up to 1A of highly efficient output current with current mode control for fast loop response. The wide 3.3V to 36V input range accommodates a variety of step-down applications in automotive input environments and is ideal for battery-powered applications due to its extremely low quiescent current.The MPQ4431 employs advanced asynchronous mode (AAM), which helps achieve high efficiency in light-load condition by scaling down the switching frequency to reduce switching and gate driving losses.Standard features include soft start (SS), external clock synchronization, enable (EN) control, and a power good (PG) indicator. High-duty cycle and low dropout mode are provided for automotive cold-crank condition.Over-current protection (OCP) with valley-current detection is employed to prevent the inductor current from running away. Hiccup mode reduces the average current in short-circuit condition greatly. Thermal shutdown provides reliable and fault-tolerant operation.The MPQ4431 is available in a QFN-16 (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.
MPQ4431GL-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 MPQ4431GL-P datasheet above.
Electronic component spot-market pricing for MPQ4431GL-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 MPQ4431GL-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.
