MIC23156: 3MHz Synchronous Buck Regulator with HyperLight Load® Mode and I2C Control

The MIC23156 is a high efficiency 1.5A synchronous buck regulator with HyperLight Load mode and dynamic voltage scaling control through I2C. The output voltage can be programmed from 0.7V up to 2.4V in 10mV steps. HyperLight Load provides very high efficiency at light loads and ultra-fast transient response. 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 MIC23156 is designed for use with 1µH, and an output capacitor as small as 2.2µF that enables a total solution size in less than 1mm in height.
