Start-up configurations

Secondary regulators mode

In this configuration, bridge 3 is configured as a single synchronous switching regulator

using its two half bridges in parallel (VAUX_(1//2)SW).

When in this mode the power-up sequence is:

1. Main switching regulator (VSWmain).

2. Auxiliary switching regulator (VAUX(1//2)_SW).

3. Main linear regulator (VLINmain).
