MIC23031 - 4MHz PWM 400mA Buck Regulator with HyperLight Load?
4MHz PWM 400mA Buck Regulator with
HyperLight Loadâ„¢ General Description Features The MIC23031 is a high-efficiency 4MHz 400mA
synchronous buck regulator with HyperLight Loadâ„¢ mode.
HyperLight Loadâ„¢ provides very-high efficiency at light
loads and ultra-fast transient response which is perfectly
suited for supplying processor core voltages. An additional
benefit of this proprietary architecture is very-low output
ripple voltage throughout the entire load range with the use
of small output capacitors. The tiny 1.6mm x 1.6mm Thin
MLFÂ® package saves precious board space and requires
only three external components.
The MIC23031 is designed for use with a very-small
inductor, down to 0.47ÂµH, and an output capacitor as small
as 2.2ÂµF that enables a sub-1mm height.
The MIC23031 has a very-low quiescent current of 21ÂµA
and achieves as high as 88% efficiency at 1mA. At higher
loads, the MIC23031 provides a constant switching
frequency around 4MHz while achieving peak efficiencies
up to 93%.
The MIC23031 is available in a 6-pin 1.6mm x 1.6mm Thin
MLFÂ® package with an operating junction temperature
range from â€“40Â°C to +125Â°C. ...
