Description
General part information
MIC23153 Series
The MIC23153 is a high efficiency 4MHz 2A synchronous buck regulator with HyperLight Load® mode, Power Good output indicator, and programmable soft-start. HyperLight Load® provides very high efficiency at light loads and ultra-fast transient response which makes the MIC23153 perfectly suited for supplying processor core voltage. 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 MIC23153 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2 µF that enables a total solution size, less than 1mm in height.
The MIC23153 has a very low quiescent current of 22µA and achieves a peak efficiency of 93% in continuous conduction mode. In discontinuous conduction mode, the MIC23153 can achieve 85% efficiency at 1mA.
