defined as percentages of the output voltage.

Therefore, the absolute levels of the thresholds

change when the output voltage setpoint is changed

either by output voltage adjustment or by margining.

In addition, a user can change type of protections

protections. These settings are programmed in the

GUI Fault Management window shown in Figure 40

or directly via the I

2C by writing into the PC1 register

shown in Figure 41.

Figure 40. Fault Management Window

Figure 41. Protection Configuration Register PC1

If the non-latching protection is selected, a POL will

attempt to restart every 130ms until the condition

that triggered the protection is removed.

When

restarting, the output voltages follow tracking and

sequencing settings.

If the latching type is selected, a POL will turn off and

stay off. The POL can be turned on after 130ms, if

the condition that caused the fault is removed and

the respective bit in the ST register was cleared, or

the Turn On command was recycled, or the input

voltage was recycled.
