Question:
Does the current limit comparator immediately switch-over to the maximum 4A current limit once the output voltage is within the 8% regulation when using a soft-start capacitor?
Answer:
With the addition of Css or soft-start capacitor connected from SS to GND, the MAX8869 output current will slowly ramp and rise during start-up. The current limit as a feature of MAX8869 which is 4A will only take effect when the output voltage is within the 8%.
