The EVQ4323-D-00A is an evaluation board for the MPQ4323, a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal high-side MOSFETs (HS-FETs) and low-side MOSFETs (LS-FETs). The MPQ4323 provides 3A of highly efficient output current (IOUT) with peak current mode control. The wide 3.3V to 36V input voltage (VIN) range and 42V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 1μA shutdown mode quiescent current (IQ) 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 that the output is within 94.5% to 105.5% of its nominal voltage. Frequency foldback helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions. The EVQ4323-D-00A is fully assembled and tested. The MPQ4323 is available in a QFN-12 (2mmx3mm) package with wettable flanks.
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.
EVQ4323-D-00A is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Development Tools. 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 EVQ4323-D-00A datasheet above.
Electronic component spot-market pricing for EVQ4323-D-00A 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 EVQ4323-D-00A 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.
