MIC4930 Datasheet | Micrel Semiconductor

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...
