The MP3446U is a high-efficiency, current-mode, synchronous boost controller with a wide 6V to 55V input voltage (VIN) range. It can operate at multiple phases for high-power applications. The MP3446U also has the capability to drive 10V MOSFETs, which greatly improves efficiency and minimizes power loss. The MP3446U provides either an I2C interface or serial peripheral interface (SPI) to configure certain key operating parameters, such as the switching frequency (fSW), current limit, light-load mode, spread spectrum, dead time, soft-start time, and slope compensation. fSW can be adjusted from 250kHz to 2.5MHz or be directly synchronized to the external source. The MP3446U also includes under-voltage lockout (UVLO), current limiting, and thermal shutdown protection. The MP3446U is available in a QFN-21 (5mmx5mm) 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.
MP3446UGUE-xxxx-Z 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 MP3446UGUE-xxxx-Z datasheet above.
Electronic component spot-market pricing for MP3446UGUE-xxxx-Z 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 MP3446UGUE-xxxx-Z 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.
