The MP4078 is an single-stage offline controller with active power factor correction (PFC) for constant voltage output applications. The device implements primary-side regulation (PSR) control without requiring a secondary feedback circuit or optocoupler for flyback applications. It is also available for non-isolated topologies (e.g. buck-boost). The device achieves ultra-low standby power consumption. Its pulse frequency modulation (PFM) implements a minimum operating frequency under no-load conditions. The MP4078 works in discontinuous conduction mode (DCM) with valley switching for improved efficiency performance. The MP4078 operates in constant-on-time (COT) mode to achieve a high power factor across the universal input. It adopts a cascode MOSFET technique to achieve fast start-up with few external components. The MP4078 integrates multiple protection features that greatly enhance system reliability and safety, including output over-voltage protection (OVP), output short-circuit protection (SCP), primary-side over-current protection (OCP), and over-temperature protection (OTP). The MP4078 is available in an SOIC-8 package. Advantages Include: Ultra-Low No Load Power, Typically< 50mW@230VAC PSR with good regulation, <±3% High PF(>0.95) and low THD (<10%) Fast startup by cascode-MOSFET technique

MP4078GS 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 MP4078GS datasheet above.
Electronic component spot-market pricing for MP4078GS 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 MP4078GS 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.
