The MIC27600 is a constant-frequency, synchronous buck regulator featuring a unique digitally modified adaptive on-time control architecture. The MIC27600 operates over an input supply range of 4.5V to 36V and provides a regulated output of up to 7A 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 300kHz.
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 digitally modified adaptive tON ripple control architecture combines the advantages of fixed-frequency operation and fast transient response in a single device.
The MIC27600 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include undervoltage lockout to ensure proper operation under power-sag conditions, internal soft-start to reduce inrush current, foldback current limit, "hiccup" mode short-circuit protection and thermal shutdown.
