The MPQ4572 is a fully integrated, fixed-frequency, synchronous step-down converter. It can achieve up to 2A of continuous output current with peak current control for excellent transient response. The wide 4.5V to 60V input voltage range accommodates a variety of step-down applications in an automotive input environment. The device’s 2μA shutdown mode quiescent current makes it ideal for battery-powered applications. The MPQ4572 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode. It employs advanced asynchronous modulation (AAM) to achieve high efficiency during 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. High-duty cycle and low-dropout mode are provided for automotive cold crank conditions. The chip provides over-current protection (OCP) with valley-current detection to avoid current runaway. It also has hiccup short-circuit protection (SCP), input under-voltage lockout (UVLO), and auto-recovery thermal protection. With internal compensation, the MPQ4572 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.
MPQ4572GQB-AEC1-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 MPQ4572GQB-AEC1-P datasheet above.
Electronic component spot-market pricing for MPQ4572GQB-AEC1-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 MPQ4572GQB-AEC1-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.
