The MPQ4456 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 1 A output with current mode control for fast loop response and easy compensation. The wide 3.8V to 36V input range accommodates a variety of step-down applications, including those in automotive systems. A 120µA operational quiescent current is suitable for use in battery-powered applications. Special controlled circuitry allows the MPQ4456 to maintain PWM operation at low output currents. This lowers noise by reducing the pulse skipping. By switching at 4MHz, the MPQ4456 prevents EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications. The MPQ4456 is available in thin 10-pin 3mm x 3mm TQFN package.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MPQ4456GQT-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 MPQ4456GQT-Z datasheet above.
Electronic component spot-market pricing for MPQ4456GQT-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 MPQ4456GQT-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.
