The MP155 is a primary-side regulator that provides accurate constant voltage regulation without the opto-coupler, and supports buck, buck-boost, and flyback topologies. An integrated 500V MOSFET simplifies the structure and reduces costs. These features make it a competitive candidate for off-line low-power applications, such as home appliances and standby power.The MP155 is a green-mode operation regulator. Both the peak current and the switching frequency decrease as the load decreases. As a result, it offers excellent efficiency performance at light load, thus improving the overall average efficiency.The MP155 features various protections such as thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open loop protection.The MP155 is available in the TSOT23-5 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.
EV155-J-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 EV155-J-00A datasheet above.
Electronic component spot-market pricing for EV155-J-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 EV155-J-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.
