The MP4317 is a configurable-frequency, synchronous, step-down switch-mode converter with integrated, internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). It can achieve up to 7A 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 an automotive input environment. The device’s 1.7μA shutdown current (ISD) makes it well-suited for battery-powered applications. The MP4317 provides high power conversion efficiency across the entire load range. It achieves high efficiency under light-load conditions by scaling down the switching frequency (fSW) to reduce the 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. High duty cycle and low-dropout mode allow the device to withstand automotive cold-crank conditions. Full protection features include frequency foldback to prevent inductor current (IL) runaway during start-up, over-current protection (OCP) with hiccup mode, and thermal shutdown for reliable, fault-tolerant operation. The MP4317 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.
MP4317GRE-Z 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 MP4317GRE-Z datasheet above.
Electronic component spot-market pricing for MP4317GRE-Z 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 MP4317GRE-Z 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.
