MIC4950

Hyper Speed Control™ 5A Buck Regulator

Features

General Description

 Input voltage: 2.7V to 5.5V

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.

 5A output current

 Up to 95% efficiency

 Up to 3.3MHz operation

 Safe start-up into a pre-biased output

 Power Good output

 Ultra-fast transient response

 Low output voltage ripple

 Low R_DSONintegrated MOSFET switches

 0.01µA shutdown current

 Thermal shutdown and current limit protection

 Output voltage as low as 0.7V

 8-Pin SOIC and 3mm × 4mm DFN-10L

 –40°C to +125°C junction temperature range

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.

Applications

 DTVs

 Set-top boxes

 Printers
