PTC0/FAULT0
XB_OUT14
25.5 Modes of operation
Under different system power modes, the module behaves as follows:
1. Run mode
All features of the module are available.
In Run mode, there are two sub-operational modes. One is
the regulation mode when V
the other is the open-loop mode when V
V. In the open-loop mode, the clamped voltage follows
with V
2. Stop mode
The module is disabled in Stop mode. All internal analog circuits are switched off.
