The EVQ4334-RH-4000-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4334GRHE-4000-AEC1, a configurable-frequency (200kHz to 2.5MHz), synchronous, step-down switching converter with an integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). The MPQ4334GRHE-4000-AEC1 provides up to 4A of highly efficient output current (IOUT) with peak current mode control. The wide 3V to 36V input voltage (VIN) range and 40V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 0.5μA shutdown mode quiescent current (IQ) 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 voltage (VOUT) is within 94.5% to 105.5% of its nominal voltage. Frequency foldback helps prevent inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout (LDO) mode are provided for automotive cold-crank conditions. The EVQ4334-RH-4000-00A is a fully assembled and tested evaluation board. The MPQ4334GRHE-4000-AEC1 is available in a QFN-14 (2.5mmx3.5mm) package with wettable flanks, and is AEC-Q100 qualified.
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.
EVQ4334-RH-4000-00A is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Development Tools. 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 EVQ4334-RH-4000-00A datasheet above.
Electronic component spot-market pricing for EVQ4334-RH-4000-00A 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 EVQ4334-RH-4000-00A 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.
