MIC23031 - 4MHz PWM 400mA Buck Regulator with HyperLight Load?
4MHz PWM 400mA Buck Regulator with
HyperLight Loadв„ў General Description Features The MIC23031 is a high-efficiency 4MHz 400mA
synchronous buck regulator with HyperLight Loadв„ў mode.
HyperLight Loadв„ў 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
MLFВ® package saves precious board space and requires
only three external components.
The MIC23031 is designed for use with a very-small
inductor, down to 0.47ВµH, and an output capacitor as small
as 2.2ВµF that enables a sub-1mm height.
The MIC23031 has a very-low quiescent current of 21ВµA
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
MLFВ® package with an operating junction temperature
range from вЂ“40В°C to +125В°C. ...
