The MP4431 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 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 environment and is ideal for battery-powered applications due to its extremely low quiescent current.The MP4431 employs advanced asynchronous mode, which helps achieve high efficiency at 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 greatly in short-circuit condition. Thermal shutdown provides reliable and fault-tolerant operation.The MP4431 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.
MP4431 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 MP4431 datasheet above.
Electronic component spot-market pricing for MP4431 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 MP4431 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.
