MIC24053 12V, 9A High-Efficiency Buck Regulator SuperSwitcher II General Description The Micrel MIC24053 is a constant-frequency, synchronous buck regulator featuring a unique adaptive on-time control architecture. The MIC24053 operates over an input supply range of 4.5V to 19V and provides a regulated output of up to 9A 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. Micrel’s Hyper Speed Control architecture allows for ultrafast transient response while reducing the output capacitance and also makes (High VIN)/(Low VOUT) operation possible.
