The MP4315 is a synchronous step-down switching converter with a configurable frequency, as well as an integrated internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). The device provides up to 5A 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. The MP4315’s low 1.7μA shutdown mode quiescent current (IQ) makes the device well-suited for battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) under light-load conditions to reduce the switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 93% to 106% of its nominal voltage. Frequency foldback helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. High duty cycle and low-dropout mode are provided for the automotive cold-crank conditions. The MP4315 is available in a QFN-20 (4mmx4mm) wettable flank package.

MP4315GRE-P 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 MP4315GRE-P datasheet above.
Electronic component spot-market pricing for MP4315GRE-P 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 MP4315GRE-P 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.
