The settings can be changed in a simple drag-and-drop fashion
and or by selecting the value from the combo box. Changes to
the VOUT_DROOP and VOUT_TRANSITION value take
place after the button on the right side next to the text box is
clicked. Other changes take place immediately and are stored
in the RAM of the IC, but need to be saved to EEPROM for
permanent storage.

IOUT WINDOW

The IOUT window sets thresholds for the output current.
Thresholds for output over current, under current, and constant
current can be programmed via this window.
Figure 55. Light Load Settings in IOUT Window
Additionally, settings for the light load mode can also be
programmed in this window through the Light Load Settings
bar on the right side. The thresholds can be programmed from
the drop-down list. The deep light load mode can be enabled, if
necessary.
It is recommended to use the manufacturer specific mode with
the maximum slew rate to control (decrease) the output voltage
when the load current crosses the constant current threshold.
The constant current threshold is set to a percentage (for
example, ±3.125% or ±12.5%) of the IOUT_OC_FAULT_LIMIT.
