MIC23201中文资料2MHz 2A Hyper Speed Control™ Synchronous Buck Regulator数据手册Microchip规格书

描述 Description

The MIC23201 is a high efficiency 2MHz 2A synchronous buck regulator with Hyper Speed Control.  Hyper Speed Control™ provides 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 MIC23201 is designed for use with a very small inductor, down to 1µH, and an output capacitor as small as 22µF that enables a total solution size, less than 1.5mm height.The MIC23201 provides a constant switching frequency around 2MHz while achieving peak efficiencies up to 90%. Also, checkout MPU power solutions with MIC23201. Go to Treelinktool under DC/DC converters and MPU Power for further information.
