The MP4054A is a primary-side-control, offline LED lighting controller. In a tiny TSOT23-8 package, it achieves high power factor (PF) and accurate LED current for isolated, single-power-stage lighting applications. This simplifies LED-lighting-system design significantly by eliminating the secondary-side feedback components and the optocoupler.The MP4054A integrates power factor correction (PFC) and valley switching mode to reduce MOSFET switching losses.The MP4054A has NTC function and allows PWM dimming.To enhance system reliability and safety, the MP4054A has multiple internally integrated protection features, including over-voltage protection (OVP), short-circuit protection (SCP), primary-side over-current protection (OCP), brown-out protection, over-temperature protection (OTP), cycle-by-cycle current limit, VCC under-voltage lockout (UVLO), and auto-restart function.
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.
MP4054A is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Driver ICs. 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 MP4054A datasheet above.
Electronic component spot-market pricing for MP4054A 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 MP4054A 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.
