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 range of output capacitor types and
values can also be accommodated.
The MIC4950 supports safe start-up into a pre-biased
output, and offers short-circuit and thermal shutdown
protections.
The MIC4950 is available in 8-Pin SOIC and 10-Pin 3mm
× 4mm DFN packages with an operating junction
temperature range from –40°C to +125°C.
