MPL Optimized Performance with MPS Inductor The MP4571 is a fully integrated, fixed-frequency, synchronous step-down converter. It can achieve up to 1A 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. A 2μA shutdown mode quiescent current makes it ideal for battery-powered applications. The MP4571 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode, and is available in a 12-pin QFN package. The MP4571 employs advanced asynchronous modulation (AAM), which achieves high efficiency during light load by scaling down the frequency to reduce the switching and gate driver losses. The MP4571 offers standard features including built-in soft start, enable control, and a power good indicator. High duty cycle and low-dropout mode are provided for automotive cold crank conditions. In addition, the chip provides over-current protection with valley current detection, which helps prevent current runaway. It also has hiccup short-circuit protection (SCP), input under-voltage lockout (UVLO), and auto-recovery thermal protection. With internal compensation, the MP4571 offers a very compact solution with a minimum 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.
MP4571GQB-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 MP4571GQB-Z datasheet above.
Electronic component spot-market pricing for MP4571GQB-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 MP4571GQB-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.
