Product Details
Key Features

The MPQ4576 is a fully integrated, fixed-frequency, synchronous step-down converter. The device can achieve up to 600mA of continuous output current (IOUT) with peak current control for excellent transient response. The wide 4.5V to 60V input voltage (VIN) range accommodates a variety of step-down applications in automotive input environments. The device’s 2μA shutdown mode quiescent current (IQ) makes it ideal for battery-powered applications. The MPQ4576 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode. The device employs advanced asynchronous modulation (AAM) mode to achieve high efficiency under light-load conditions by scaling down the frequency to reduce switching and gate driver losses. Standard features include built-in soft start, enable control, and power good indication. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions. The MQ4576 provides over-current protection (OCP) with valley current detection to avoid current runaway. It also provides hiccup short-circuit protection (SCP), input under-voltage lockout (UVLO), and auto-recovery thermal protection. With internal compensation, the MPQ4576 can offer a very compact solution with a minimal number of readily available, standard external components. It is available in a QFN-12 (2.5mmx3mm) 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.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is MPQ4576GQBE-Z, and what package does it use?

MPQ4576GQBE-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 MPQ4576GQBE-Z datasheet above.

Why is dynamic quotation used instead of a fixed price for MPQ4576GQBE-Z?

Electronic component spot-market pricing for MPQ4576GQBE-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.

What is the delivery timeline after placing an order for MPQ4576GQBE-Z?

Lead times for MPQ4576GQBE-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.
