MIC23155 Datasheet | Micrel Semiconductor

Description Features The MIC23155 is a high-efficiency 3MHz 2A synchronous buck regulator with Hyper Light Load mode, power good output indicator, and programmable soft start. Hyper Light Load provides very high efficiency at light loads and ultrafast transient response which makes the MIC23155 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 2.5mm x 2.5mm Thin DFN package saves precious board space and requires only four external ponents. The MIC23155 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2µF that enables a total solution size, less than 1mm in height. The MIC23155 has a very low quiescent current of 22µA and achieves a peak efficiency of 94% in...
