The MPQ1542 is a current-mode, step-up converter with a 2A, 0.18O internal switch that provides a highly efficient regulator with fast response. The MPQ1542 can be operated at 700kHz or 1.3MHz, allowing for easy filtering and low noise. An external compensation pin provides flexibility in setting loop dynamics, which allows the use of small, low ESR, ceramic output capacitors. Soft start results in a small inrush current and can be programmed with an external capacitor. The MPQ1542 operates from an input voltage as low as 2.5V and can generate 12V at up to 500mA from a 5V supply. Full protection features include under-voltage lockout (UVLO), current limiting, and thermal overload protection, which prevents damage in the event of an output overload. The MPQ1542 is available in a low profile, 8-pin, MSOP package.
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.
MPQ1542 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 MPQ1542 datasheet above.
Electronic component spot-market pricing for MPQ1542 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 MPQ1542 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.
