MIC4930
Hyper Speed Control™ 3A Buck
Regulator
General Description
The MIC4930 is a high-efficiency, 3A synchronous buck
regulator with ultra-fast transient response perfectly suited for supplying processor core and I/O voltages from a 5V or 3.
3V bus.
The MIC4930 provides a switching frequency up to 3.
3MHz while achieving peak efficiencies up to 95%.
An additional benefit of high-frequency operation is very low output ripple voltage throughout the entire load range with the use of a small output capacitor.
The MIC4930 is designed for use with a very small inductor, down to 1µH, and an output ceramic capacitor as small as 10µF without the need for external ripple injection.
A wide range of o...
