Secondary regulators mode
In this configuration, bridge 3 is configured as a single synchronous switching regulator
using its two half bridges in parallel (V
using its two half bridges in parallel (V
AUX_(1//2)SW
).
When in this mode the power-up sequence is:
1.
Main switching regulator (V
SWmain
).
2.
Auxiliary switching regulator (V
AUX(1//2)_SW
).
3.
Main linear regulator (V
LINmain
).
