The MPQ4331-AEC1 family of converters are high-frequency, synchronous, step-down switching regulators with integrated, internal high-side and low-side power MOSFETs (HS-FETs and LSFETs, respectively). The device provides 0.5A to 1A of highly efficient output current (IOUT) with peak current mode control. The wide 3V to 36V input voltage (VIN) range and 40V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 1μA shutdown-mode quiescent current 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) under light-load conditions to reduce the switching and gate driving 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 MPQ4331-AEC1 is available in a space-saving TSOT23-8 package, and 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.
MPQ4331-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 MPQ4331-AEC1 datasheet above.
Electronic component spot-market pricing for MPQ4331-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 MPQ4331-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.
