The MPQ4469 is a step-down switching regulator with an integrated internal high-side power MOSFET and a configurable frequency from 350kHz to 2.5MHz. It provides up to 5A 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. The device is ideal for battery-powered applications due to its extremely low quiescent current. The MPQ4469 employs AAM (advanced asynchronous modulation) mode, which achieves high efficiency in light-load conditions by scaling down the switching frequency to reduce switching and gate-driving losses. Standard features include soft start (SS), external clock sync, enable (EN) control, and a power good (PG) indicator. High duty cycle and low-dropout mode are provided for automotive cold crank conditions. Over-current protection (OCP) is employed to prevent the inductor current from running away. Hiccup mode greatly reduces the average current in short circuit conditions. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ4469 is available in a QFN-20 (4mmx5mm) 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.
MPQ4469-AEC1 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 MPQ4469-AEC1 datasheet above.
Electronic component spot-market pricing for MPQ4469-AEC1 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 MPQ4469-AEC1 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.
