The MPM3840 is a monolithic step-down converter with built-in internal power MOSFETs and inductor. The DC-DC module is housed in a small surface QFN package which is sized 3mm width by 5mm length by 1.6mm height. It can provide 4A continuous output current from a 2.8V to 5.5V input voltage with excellent load and line regulation. The MPM3840 is ideal for powering portable equipment that runs with a single cell Lithium-Ion (Li+) Battery. The output voltage can be regulated as low as 0.6V. Only input, output capacitors and FB resistors are needed to complete the design.The Constant-On-time (COT) control scheme provides fast transient response high light-load efficiency and easy loop stabilization. Fault condition protection includes cycle-by-cycle current limit and thermal shutdown.The MPM3840 requires a minimum number of readily available standard external components and is available in an ultra-small QFN-20 (3mmx5mm) package.
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.
EVM3840-QV-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 EVM3840-QV-00A datasheet above.
Electronic component spot-market pricing for EVM3840-QV-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 EVM3840-QV-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.
