The MP4573 is a fully integrated, fixed-frequency, synchronous step-down converter. It can achieve up to 2.5A 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 current makes it ideal for battery-powered applications. The MP4573’s integrated, internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively) provide high efficiency without the need for an external Schottky diode. Advanced asynchronous modulation (AAM) mode achieves high efficiency under light-load conditions by scaling down the frequency to reduce switching and gate driver losses. Features include built-in soft start (SS), enable (EN) control, and power good (PG) indication. The high duty cycle and low-dropout (LDO) mode allow the device to withstand automotive cold crank conditions. The MP4573 employs over-current protection (OCP) with valley current detection to avoid current runaway. It also features short-circuit protection (SCP) with hiccup mode, input under-voltage lockout (UVLO), and auto-recovery thermal protection. With internal compensation, the MP4573 offers an ultra-compact solution that requires a minimal number of readily available, standard external components. It is available in a QFN-12 (2.5mmx3mm) package.

MP4573GQBE 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 MP4573GQBE datasheet above.
Electronic component spot-market pricing for MP4573GQBE 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 MP4573GQBE 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.
