The EVQ4312-R-01A evaluation board is designed to demonstrate the capabilities of the MPQ4312, a synchronous, step-down switching regulator with a configurable frequency and an integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). It provides up to 2A of highly efficient output current (IOUT), with current mode control for fast loop response. The wide 3.3V to 45V input voltage (VIN) range accommodates a variety of step-down applications in automotive input environments. A 1.7μA 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) under light-load conditions to reduce switching and gate driver losses. 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 mode are provided for automotive cold-crank conditions. The EVQ4312-R-01A is fully assembled and tested. The MPQ4312 is available in a QFN-20 (4mmx4mm) package with wettable flanks, and is AEC-Q100 Grade 1 qualified.
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.
EVQ4312-R-01A 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 EVQ4312-R-01A datasheet above.
Electronic component spot-market pricing for EVQ4312-R-01A 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 EVQ4312-R-01A 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.
