Features & Applications

The MIC2164-3YMM is a constant frequency, synchronous buck controller featuring adaptive on-time control. The MIC2164/-2/-3 are the first products in the new Hyper Speed ControlTM family of buck controllers introduced by Micrel. The MIC2164/-2/-3 controllers operate over an input supply range of 3 V to 28 V, and are independent of the IC supply voltage.

The devices are capable of supplying 25 A output current. While the MIC2164 operates at 300 kHz, the MIC2164-2 operates at 600 kHz, and the MIC2164-3 operates at 1 MHz. A unique Hyper Speed ControlTM architecture allows for ultrafast transient response while reducing the output capacitance and also makes High VIN/Low VOUT operation possible. The MIC2164/-2/-3 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 controllers are available in a 10-pin MSOP (MAX1954A compatible) package with a junction operating range from –40°C to +125°C.
