MIC26903-ZA 28V, 9A Hyper Speed Control Synchronous DC-to-DC Buck Regulator SuperSwitcher™ II General Description The Micrel MIC26903-ZA is a constant-frequency, synchronous buck regulator featuring a unique adaptive on-time control architecture. The MIC26903-ZA operates over an input supply range of 4.5V to 28V and provides a regulated output of up to 9A of output current. The output voltage is adjustable down to 0.6V with a guaranteed accuracy of ±1%, and the device operates at a switching frequency of 600kHz. Micrel’s Hyper Speed Control architecture allows for ultra-fast transient response while reducing the output capacitance and also makes (High VIN)/(Low VOUT) operation possible.
