The EV9931-R-00A evaluation board is designed to demonstrate the capabilities of the MP9931, a high-voltage, synchronous, step-down, switching regulator controller. The evaluation board can achieve up to 20A of continuous output current (IOUT) across a 25V to 100V input voltage (VIN), with excellent load and line regulation. The MP9931 adopts constant-on-time (COT) control internally to provide fast transient response, easy loop design, and tight output regulation. Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown. It is recommended to read the MP9931 datasheet prior to making any changes to the EV9931-R-00A.
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.
EV9931-R-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 EV9931-R-00A datasheet above.
Electronic component spot-market pricing for EV9931-R-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 EV9931-R-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.
