MIC24055 - 12A High-Efficiency Buck Regulator

Features

  • The Micrel MIC24055 is a constant-frequency, synchronous buck regulator featuring a unique adaptive on-time control architecture. The MIC24055 operates over an input supply range of 4.5V to 19V and provides a regulated output of up to 12A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%, and the device operates at a switching frequency of 600kHz.
  • Hyper Speed Control architecture enables - High delta V operation (VIN = 19V and VOUT = 0.
