The LM5642 features analog soft-start circuitry that is independent of the output load and output capacitance making the soft-start behavior more predictable and controllable than traditional soft-start circuits. Over-voltage protection is available for both outputs. A UVDelay pin is also available to allow delayed shut off time for the IC during an output under-voltage event.
