The MP4581 is a high-efficiency, synchronous step-down converter with integrated power MOSFETs. It provides 0.8A of output current (IOUT) in a buck topology from an input power supply of up to 100V. The MP4581 features constant-on-time (COT) control, which provides fast transient response and facilitates loop stabilization. The configurable operation frequency can be set between 100kHz to 1MHz via an external resistor. The MP4581 supports high-efficiency pulse-skip mode (PSM) while operating under light-load conditions. The valley current limit circuits protect against overload and short-circuit conditions. The MP4581 is available in a SOIC-8EP package.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MP4581GN-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 MP4581GN-P datasheet above.
Electronic component spot-market pricing for MP4581GN-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 MP4581GN-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.
