The MPQ4328 is a configurable-frequency (200kHz to 2.5MHz), synchronous, step-down switching converter with an integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). The device can achieve up to 4A of highly efficient output current (IOUT) with peak current mode control. The wide 3.3V to 36V input voltage (VIN) range accommodates a variety of step-down applications in an automotive input environment. A 1μA quiescent current (IQ) in shutdown mode allows the device 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) at light loads to reduce switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 94.5% to 105.5% of its nominal voltage. Frequency foldback prevents inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low drop-out mode are provided for automotive cold crank conditions. The MPQ4328 is available in a QFN-14 (4mmx4mm) 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.
MPQ4328GRE-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 MPQ4328GRE-AEC1-Z datasheet above.
Electronic component spot-market pricing for MPQ4328GRE-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 MPQ4328GRE-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.
