Device Overview

Summary

The MIC23156 is a high-efficiency 1.5A synchronous buck regulator with HyperLight Load® mode and dynamic voltage scaling control through I2C. HyperLight Load provides very high efficiency at light loads and ultra-fast transient response. The ability to dynamically change the output voltage and maintain high output voltage accuracy make the MIC23156 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. Fast mode plus I2C provides output voltage and chip enable/disable control from standard I2C bus with I2C clock rates of 100kHz, 400kHz, and 1MHz.

The MIC23156 is designed for use with 1µH, and an output capacitor as small as 2.2µF that enables a total solution size, less than 1mm in height.

The MIC23156 is available in both 16-ball, 0.4mm Pitch, 1.81mm x 1.71mm wafer level chip scale (WLCSP) with an operating junction temperature range of -40°C to +125°C.
