MIC23153
4MHz PWM 2A Buck Regulator with
HyperLight Load? and Power Good
General Description
Features
capacitors. The tiny 2.5mm x 2.5mm Thin MLF package
? 35mVpp ripple in HyperLight Load mode
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
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
?
saves precious board space and requires only four
external components.
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
