The MPQ4384-AEC1 is a configurable-frequency (200kHz to 2.5MHz), synchronous step-down switching regulator with an integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). It provides a highly efficient, 12A to 18A output current (IOUT) with fixed-frequency, Zero-Delay pulse-width modulation (PWM) (ZDPTM) control for an optimal transient response. The wide 3.3V to 36V input voltage (VIN) range accommodates a variety of step-down applications in the automotive environment. A 1.5μA shutdown-mode quiescent current (IQ) allows the MPQ4384-AEC1 to be used in battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) under light-load conditions to reduce switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 95% to 105% of its nominal voltage. Frequency foldback helps prevent inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout (LDO) mode are provided for automotive cold-crank conditions. The MPQ4384-AEC1 is available in a TQFN-32 (5mmx6mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
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.
MPQ4384GQJTHE-xxxx-AEC1-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 MPQ4384GQJTHE-xxxx-AEC1-Z datasheet above.
Electronic component spot-market pricing for MPQ4384GQJTHE-xxxx-AEC1-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 MPQ4384GQJTHE-xxxx-AEC1-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.
