The MPQ4390-AEC1 is a high current output, synchronous, dual buck converter that is designed for automotive applications. The device provides a wide input voltage (VIN) range, fast transient response, high efficiency, rich monitoring and protection features, and good EMI performance. The MPQ4390-AEC1 can be selected to operate in either 2-channel mode or single-output multi-phase mode. For 2-channel mode, the output current (IOUT) for each buck reaches up to 7A, and has a 12A capability with a heat sink. Multiple MPQ4390 chips connected in parallel can also support 4-phase or 8-phase modes. The switching frequency (fSW) is configurable between 200kHz and 2.2MHz, or it can be synchronized to an external clock signal. The MPQ4390-AEC1 also provides the frequency spread-spectrum (FSS) function to improve EMI performance. Comprehensive protection features include input under-voltage lockout (UVLO), input over-voltage protection (OVP), cycle-by-cycle peak current limiting, output OVP, output short-circuit protection (SCP), and thermal shutdown. Different configurations can easily be configured via three selectable interfaces, including a serial peripheral interface (SPI) and an I2C. The one-time programmable (OTP) memory allows for vast flexibility via configurability. The MPQ4390-AEC1 is available in a TQFN-28 (5mmx6mm) package, and is available in AEC-Q100 Grade 1.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MPQ4390GQJTE-xxxx-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 MPQ4390GQJTE-xxxx-AEC1-P datasheet above.
Electronic component spot-market pricing for MPQ4390GQJTE-xxxx-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 MPQ4390GQJTE-xxxx-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.
