The MPQ3445-AEC1 is a high-efficiency, current-mode, synchronous boost controller with a wide input voltage (VIN) range. It can be used as a pre-boost controller to maintain the output voltage (VOUT) from a vehicle battery during automotive cranking or from a backup battery. The MPQ3445-AEC1 has the capability to drive 10V MOSFETs, greatly improving efficiency and minimizing power loss. The MPQ3445-AEC1 provides either a configurable I2C (default) or SPI interface to configure some key operating parameters, such as the switching frequency (fSW), current limit, light-load mode, frequency spread spectrum (FSS), dead time (DT), and slope compensation. fSW can be adjusted from 250kHz to 2.5MHz or synchronized directly to an external source. In the event that VOUT exceeds the preset bypass threshold and VIN exceeds VOUT at the same time, the MPQ3445-AEC1 operates in low quiescent current (IQ) bypass mode. When VOUT falls below the wake threshold, the part exits bypass mode and resumes normal operation with the high-side MOSFET and low-side MOSFET (HS-FET and LS-FET, respectively) switching to regulate the output. Protection features include under-voltage lockout (UVLO), current limit, and thermal shutdown. The MPQ3445-AEC1 is available in a QFN-21 (5mmx5mm) package with wettable flanks, and is AEC-Q100 Grade 1 qualified.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MPQ3445GUE-xxxx-AEC1-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 MPQ3445GUE-xxxx-AEC1-Z datasheet above.
Electronic component spot-market pricing for MPQ3445GUE-xxxx-AEC1-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 MPQ3445GUE-xxxx-AEC1-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.
