MIC23153YMT TR

The MIC23153YMT TR is a high-efficiency 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 ultrafast transient response which makes the MIC23153 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. It 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 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.
