MIC26603-ZA Datasheet | Micrel Semiconductor

28V, 6A Hyper Speed Control Synchronous DC-to-DC Buck Regulator Super Switcher™ II General Description The Micrel MIC26603-ZA is a constant-frequency, synchronous buck regulator featuring a unique adaptive ON-time control architecture. The MIC26603-ZA operates over an input supply range of 4.5V to 28V and provides a regulated output of up to 6A 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 600k Hz. 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. This adaptive t ON ripple control architecture bines the advantages of fixed-frequency operation and fast transient response in a single device. The MIC26603-ZA offers a full suite of Features to ensure protection of the IC during fault conditions. These include undervoltage lockout to...
