GENERAL DESCRIPTION
The Micrel 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 from 0.8V to 5.5V. A unique Hyper Speed Control™ architecture enables ultra-fast transient response while reducing the output capacitance and also makes High VIN/Low VOUT operation possible. A UVLO feature is provided to ensure proper operation under power-sag conditions to prevent the external power MOSFET from over heating. Also, a soft-start feature is provide
