MIC23155
3MHz PWM 2A Buck Regulator with
HyperLight Load ? and Power Good
General Description
Features
The MIC23155 is a high-efficiency 3MHz 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 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 components.
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 continuous
conduction mode. In discontinuous conduction mode, the
MIC23155 can achieve 85% efficiency at 1mA.
The MIC23155 is available in a 10-pin 2.5mm x 2.5mm
