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 0.47 µH, and an output capacitor as small as 2.2 µF 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 1 mA.
At higher loads, the MIC23031 provides a constant switching frequency around 4 MHz 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.
