General Description
The MIC23031 is a high-efficiency, 4 MHz, 400 mA
synchronous buck regulator with HyperLight Load®
mode. HyperLight Load provides very high efficiency at
light loads and ultra-fast transient response that is
perfectly suited for supplying processor core voltages.
An additional benefit of this proprietary architecture is
the very low output ripple voltage throughout the entire
load range with the use of small output capacitors. The
tiny 1.6 mm x 1.6 mm TDFN package saves precious
board space and requires only three external
components.
The MIC23031 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 sub 1 mm height.
The MIC23031 has a very low quiescent current of
21 µA and achieves as high as 88% efficiency at 1mA.
At higher loads, the MIC23031 provides a constant
switching frequency around 4MHz while achieving
peak efficiencies up to 93%.
The MIC23031 is available in a 6-pin 1.6 mm x 1.6 mm
TDFN package with an operating junction temperature
range of –40°C to +125°C.
