Overview

MIC4950 Hyper Speed Control™ 5A Buck Regulator General Description The MIC4950 is a high-efficiency, 5A synchronous buck regulator with ultra-fast transient response.
It is perfectly suited for supplying processor core and I/O voltages from a 5V or 3.
3V bus.
The MIC4950 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 MIC4950 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 ra...
