Working Principle

The MAX16963RATEA/V+T works using an hysteretic voltage regulator technique that compares a reference voltage with feedback from the output voltage. When the output voltage is too low, the controller switches the low-side MOSFET on, allowing current to flow through the inductor, raising the output voltage; when the output voltage is too high, the controller switches the high-side MOSFET on, allowing current to flow from the output to ground, lowering the output voltage. The result is a regulated output voltage.

The MAX16963RATEA/V+T also integrates a synchronous driver with a proprietary slew-rate control programming technique to provide superior transient response. This integrated driver also provides high-side drive capability. This slew-rate control technique utilizes a spike limiting circuit, reducing the switching frequency at low duty cycles to ensure the output voltage remains stable throughout load transients.

At high duty cycle, the switching frequency is increased, providing faster transient response. This improves the dynamic response of the regulator during load transients, ensuring voltage stability during load changes.
