MIC23150
4MHz PWM 2A Buck Regulator with
HyperLight Load?
General Description
Features
The MIC23150 is a high efficiency 4MHz 2A synchronous
buck regulator with HyperLight Load? mode. HyperLight
Load? provides very high efficiency at light loads and
ultra-fast transient response which is 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 2mm x 2mm Thin MLF ?
package saves precious board space and requires only
three external components.
The MIC23150 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
height.
The MIC23150 has a very low quiescent current of 23μA
and achieves a peak efficiency of 93% in continuous
conduction mode. In discontinuous conduction mode, the
