The MPQ9843 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range. The switching frequency is programmable or can be synchronized to an external clock in the range of 350kHz to 2.5MHz. Synchronous operation and ultra-low 14μA sleep mode quiescent current provides high efficiency over the output current load range, allowing the MPQ9843 to be used in a variety of step-down applications in automotive input environments and battery-powered applications. Peak-current-mode operation provides fast transient response and eases loop stabilization. The excellent low dropout performance allows the MPQ9843 to be used in high duty cycle applications. Full protection features include over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown. An open-drain power good (PG) signal indicates when the output is within 10% of its nominal voltage. The MPQ9843 is available in a space-saving 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.
MPQ9843GL 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 MPQ9843GL datasheet above.
Electronic component spot-market pricing for MPQ9843GL 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 MPQ9843GL 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.
