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 capacitors. The tiny 2.5mm x 2.5mm Thin MLF® package 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 MIC23153 can achieve 85% efficiency at 1mA.
The MIC23153 is available in 10-pin 2.5mm x 2.5mm Thin MLF® package with an operating junction temperature range from -40°C to +125°C.
