Primary regulator mode (KP)
In this configuration bridge 4 can be configured by firmware while bridge 3 is configured as
two separate synchronous switching regulators. The last regulator in the sequence
(V
When in this mode the power-up sequence is:

3.
Regulators mode
In this configuration bridge 4 can be configured by firmware while bridge 3 is configured as
two separate synchronous switching regulators, but the start up sequence is different
previous one.
