8MHz PWM 400mA Buck Regulator with
HyperLight Loadв„ў General Description Features The MIC23030 is a high efficiency 8MHz 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.
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 MIC23030 is designed for use with a very small
inductor, down to 0.47ВµH, and an output capacitor as small
as 2.2 ВµF that enables a sub-1mm height.
The MIC23030 has a very low quiescent current of 21ВµA
and achieves as high as 83% efficiency at 1mA. At higher
loads, the MIC23030 provides a constant switching
frequency around 8MHz while achieving peak efficiencies
up to 91%.
The MIC23030 is available in a 6-pin 1.6mm x 1.6mm Thin
MLFВ® package with an operating junction temperature …
