The MIC33163/4 is a highly efficient synchronous buck regulator with integrated inductor which provides the optimal trade-off between footprint and efficiency. The MIC33163/4 operates at 4MHz switching frequency and provides up to 1A output current. In addition, the 100% duty cycle and HLL mode of operation delivers very-high efficiency at light loads and ultra-fast transient response which makes the MIC33163/4 perfectly suited for any space constrained application and great alternative for low dropout regulators. 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 MIC33163/4 provides a small compact total solution size of 4.6mm x 7mm with very few tiny external components. At higher loads, the MIC33163/4 provides a constant switching frequency around 4MHz while achieving peak efficiencies up to 93%. It also includes under-voltage lockout to ensure proper operation under power-sag conditions, internal softstart to reduce inrush current, fold-back current limit, power good indicator and thermal shutdown. The MIC33163/4 is available in 20-pin 2.5mm × 3.0mm x 1.1mm QFN 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.
MIC33163 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 MIC33163 datasheet above.
Electronic component spot-market pricing for MIC33163 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 MIC33163 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.
