Product Details
Key Features

The EV5403-QB-02A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP5403. The MP5403 is a monolithic power management unit containing two high efficiency step-down switching converters and a load switch. The two regulators supply current up to 3.5A and 2.5A separately and the load switch supplies up to 3A load current with extremely low RON resistance. With the input range up to 6V, the MP5403 is ideal for powering ASIC and SOC for Solid-State Drive or other compact power systems. The MP5403 requires a minimum number of readily available standard external components and is available in a small QFN20 (2.5mmx3mm) package.

Product FAQ
Purchasing FAQ

What type of component is EV5403-QB-02A, and what package does it use?

EV5403-QB-02A 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 EV5403-QB-02A datasheet above.

Why is pricing for EV5403-QB-02A available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for EV5403-QB-02A 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.

How quickly can EV5403-QB-02A be shipped once quoted?

Lead times for EV5403-QB-02A 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.
