The EVQ4589-QVE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4589-AEC1, a 9μA quiescent current (IQ), synchronous step-down converter with integrated high-side and low-side MOSFETs (HS-FET and LS-FET, respectively). It supports up to 0.8A of output current (IOUT) with internal compensation. High power conversion efficiency across a wide load range is achieved with power-save mode (PSM) and a low IQ under light-load conditions to reduce switching and gate driver losses. To achieve a small output ripple under light loads, pulling the MODE/SYNC pin high sets the part to forced continuous conduction mode (FCCM). The switching frequency (fSW) is always fixed at 400kHz for all load conditions. Full protection features include over-current protection (OCP), short-circuit protection (SCP) with hiccup mode, output over-voltage protection (OVP), and over-temperature protection (OTP). The MPQ4589-AEC1 is available in a QFN-19 (3mmx5mm) package, and 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.
EVQ4589-QVE-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 EVQ4589-QVE-00A datasheet above.
Electronic component spot-market pricing for EVQ4589-QVE-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 EVQ4589-QVE-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.
