The MPQ73351FS-AEC1 is an ASIL-D, high output current (IOUT), synchronous, dual buck converter designed for automotive safety applications. It has a wide input voltage (VIN) range, fast transient response, high efficiency, rich monitoring and protection features, and good EMI performance. The device can be selected to operate in either 2-channel mode or single-output multi-phase mode. For 2-channel mode, IOUT for each buck is up to 7A with the capability for 12A with a heatsink. Multiple MPQ73351FS-AEC1 chips in parallel can also support four-phase or eight-phase modes. The switching frequency (fSW) is configurable from 200kHz to 2.2MHz, or it can be synchronized with an external clock signal. Frequency spread spectrum (FSS) is featured 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 the selectable SPI or I2C interface. The one-time programmable (OTP) memory allows for vast flexibility through programmability. The MPQ73351FS-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.
MPQ73351FSGQJTE-0000AEC-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 MPQ73351FSGQJTE-0000AEC-Z datasheet above.
Electronic component spot-market pricing for MPQ73351FSGQJTE-0000AEC-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 MPQ73351FSGQJTE-0000AEC-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.
