The MP4575 is a frequency-programmable, step-down, switching converter with integrated, internal, high-side and low-side power MOSFETs. The MP4575 can provide 5A of continuous output current with peak current control for excellent transient response and efficiency performance. The wide 4.5V to 55V input voltage range accommodates a variety of step-down applications, including industrial, PoE, automotive, and printers with a DC high-voltage bus. The MP4575 uses peak-current-mode control to regulate the output voltage. The MP4575 provides over-current protection (OCP) with valley current detection, which is used to prevent the current from running away. The MP4575 also has accurate and reliable over-voltage protection (OVP) and auto-recovery thermal protection. An optional external soft start is available. Enable and power good indication functions can be used to track the power easily. To increase efficiency, the MP4575 scales down the switching frequency automatically when the load is light. Meanwhile, the low-side MOSFET is turned off to reduce driver loss when zero inductor current is detected. Synchronous operation mode with the integrated low-side MOSFET is useful for reducing conduction loss and reducing external components space to save cost.The MP4575 is available in a TSSOP-20 EP package with an exposed pad.
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.
MP4575 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 MP4575 datasheet above.
Electronic component spot-market pricing for MP4575 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 MP4575 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.
