Device Overview

Summary

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.
