The MPQ4345 is a synchronous, step-down switching converter with a 350kHz to 2.5MHz configurable frequency and an integrated, internal high-side MOSFET (HS-FET) and low side MOSFET (LS-FET). The device provides up to 2A of highly efficient output current (IOUT) with fixed-frequency, zero-delay pulse-width modulation (PWM) control to optimize transient response. The wide 3.3V to 36V input voltage (VIN) range and 42V load dump tolerance accommodate a variety of step-down applications in automotive input environments. A 1μA quiescent current (IQ) in shutdown mode allows the device to be used in battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) under light-load conditions to reduce switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 94% to 106% of its nominal voltage. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout (LDO) mode are provided for automotive cold-crank conditions. The MPQ4345 is available in a QFN-17 (3mmx4mm) package, and is available in AEC-Q100 Grade 1.
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.
MPQ4345GLE-5-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 MPQ4345GLE-5-AEC1-Z datasheet above.
Electronic component spot-market pricing for MPQ4345GLE-5-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 MPQ4345GLE-5-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.
