The MP4313 is a configurable-frequency, synchronous, step-down switching converter with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). It can achieve up to 3A of highly efficient output current (IOUT) with current mode control for fast loop response. The wide 3.3V to 45V input voltage (VIN) range accommodates a variety of step-down applications in automotive input environments. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions. The 1.7μA shutdown current (ISD) allows the device to be used in battery-powered applications. High power conversion efficiency across the entire load range is achieved by scaling down the switching frequency (fSW) under light-load conditions. This reduces switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 95% to 105% of its nominal voltage. Frequency foldback prevents inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. The MP4313 is available in a QFN-20 (4mmx4mm) 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.
MP4313 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 MP4313 datasheet above.
Electronic component spot-market pricing for MP4313 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 MP4313 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.
