GENERAL DESCRIPTION
The Micrel MIC2164/-2/-3/C are constant-frequency, synchronous buck controllers featuring adaptive on-time control. The MIC2164/-2/-3/C are the first products in the new Hyper Speed Control™ family of buck controllers introduced by Micrel. The MIC2164/-2/-3/C controllers operate over an input supply range of 3V to 28V, and are independent of the IC supply voltage. The devices are capable of supplying 25A output current. While the MIC2164 operates at 300kHz, the MIC2164-2 operates at 600kHz, and the MIC2164-3 operates at 1MHz. A unique Hyper Speed Control architecture allows for ultra-fast transient response while reducing the output capacitance and also makes High VIN/Low VOUT operation possible. A UVLO feature is provided to ens
