The MIC23163/4 is a high-efficiency, 4MHz, 2A, synchronous buck regulator with HyperLight Load® (HLL) mode and maximum 100% duty cycle. HLL provides very-high efficiency at light loads and ultra-fast transient response which makes the MIC23163/4 perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors. The tiny 2.0mm — 2.0mm DFN package saves precious board space and requires only three external components.
The MIC23163/4 is designed for use with a very small 0.47µH inductor and 10µF output capacitor that enables a total solution size, less than 1mm height.
The MIC23163/4 has a very low quiescent current of 33µA and achieves as high as 85% efficiency at 1mA. At higher loads, the MIC23163/4 provides a constant switching frequency around 4MHz while achieving peak efficiencies up to 93%. The MIC23164 incorporates an active discharge feature that switches an 180ω FET to ground to discharge the output when the part is disabled.
The MIC23163/4 is available in 10-pin 2.0mm — 2.0mm DFN 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.
MIC23164 is an authentic electronic component manufactured by Microchip, categorized under Unclassified. 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 MIC23164 datasheet above.
Electronic component spot-market pricing for MIC23164 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 MIC23164 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.
