The Micrel MIC2174/MIC2174C is a fixed frequency, synchronous buck controller featuring adaptive on-time control. The MIC2174/MIC2174C operates over an input supply range of 3V to 40V at a fixed switching frequency of 300kHz and is capable of driving 25A of output current. The output voltage is adjustable down to 0.8V.
A unique Hyper Speed Control™ architecture allows for ultra fast transient response while reducing the output capacitance and also makes ultra fast transient response while reducing the output capacitance and also extremely low duty-cycle operation possible. The MIC2174/MIC2174C utilizes an adaptive tON ripple controlled architecture. A UVLO is provided to ensure proper operation under power-sag conditions to prevent the external power MOSFET from overheating. A soft-start is provided to reduce inrush current. Foldback current limit and "hiccup" mode short-circuit protection ensure FET and load protection.
The MIC2174/MIC2174C is available in a 10-pin MSOP (MAX1954A-compatible) package with an operating junction temperature range from -40°C to +125°C.
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.
MIC2174 is an authentic electronic component manufactured by Microchip, 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 MIC2174 datasheet above.
Electronic component spot-market pricing for MIC2174 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 MIC2174 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.
