The MP174A is a primary-side regulator that provides accurate constant voltage (CV) regulation without an opto-coupler. It supports buck, buck-boost, boost, and flyback topologies. It has an integrated 700V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for offline, low-power applications such as home appliances and standby power. The device is a green mode operation regulator. Both the peak current and switching frequency decrease as the load decreases. This feature provides excellent efficiency at light-load and improves the overall average efficiency. The MP174A has various protection features, including thermal shutdown (OTP), VCC under-voltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and open-loop detection. It is available in small TSOT23-5 and SOIC-8 packages.
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.
MP174A is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management 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 MP174A datasheet above.
Electronic component spot-market pricing for MP174A 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 MP174A 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.
