MIC23150
4MHz, PWM, 2A Buck Regulator with
HyperLight LoadВ® General Description
The MIC23150 is a high-efficiency 4MHz 2A synchronous
В®
buck regulator with HyperLight Load mode. HyperLight
Load provides very high efficiency at light loads and ultrafast 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 Г— 2mm Thin DFN
(TDFN) package saves precious board space and requires
only three external components.
The MIC23150 is designed for use with a very small
inductor, down to 0.47ВµH, and an output capacitor as small
as 2.2 ВµF that enables a total solution size, less than 1mm
height.
The MIC23150 has a very low quiescent current of 23ВµA
and achieves a peak efficiency of 93% in continuous
conduction mode. In discontinuous conduction mode, the
MIC23150 can achieve 87% efficiency at 1mA.
The MIC23150 is available in 8-pin 2mm Г— 2mm Thin DFN
package with an operating junction temperature range …
