Description

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.

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. The MIC2164/-2/-3/C controllers utilizes an architecture which is adaptive tON ripple controlled. A UVLO feature is provided to ensure proper operation under power-sag conditions to prevent the external power MOSFET from overheating. A soft start feature is provided to reduce the inrush current. Foldback current limit and "hiccup" mode short-circuit protection ensure FET and load protection.

The MIC2164/-2/-3/C controllers are available in a 10-pin MSOP (MAX1954A-compatible) package with a junction operating range from -40°C to +125°C.
