The EV4057A-K-00A evaluation board is designed to demonstrate the capabilities of the MP4057A. The MP4057A is a single-stage, single-chip solution for smart LED applications. It can regulate the LED current with PSR control, and meanwhile supply power for MCU/wireless module. It is an ideal solution for smart LED lighting because of its simple design, few external components, and low cost. The EV4057A-K-00A adopts the flyback topology to drive a 21V LED and supply a 3.3V/50mA smart control module. Determined by the customer specification about the standby power, the EV4057A-K-00A can be configured for two kinds of circuits. The default EVB board is designed for less than 30mW standby power. It can also be configured for 15mW standby power.
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.
EV4057A-K-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 EV4057A-K-00A datasheet above.
Electronic component spot-market pricing for EV4057A-K-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 EV4057A-K-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.
