The MIC2166 operates over a supply range of 4.5V to 28V. It has an internal linear regulator which provides a regulated 5V supply to power the internal control circuitry. MIC2166 operates at a constant 600kHz switching frequency and can be used to drive up to 25A of output current. The output voltage is adjustable down to 0.8V. A unique Hyper Speed ControlTM architecture enables ultra-fast transient response while reducing the output capacitance and also makes High VIN/Low VOUT operation possible.
