Figure 7. Initial start-up phase

7.1.2

Active mode

It is the normal operational mode. During this state the external MOSFET is driven

accordingly to signals coming from the application in order to regulate the desired output

parameter in the closed loop (peak current control method).

7.1.3

Stop mode

This state is intended to stop the switching activity without turning off the entire function set,

to quickly restart when abnormal or disabling conditions end. During this state the power

consumption is not minimized and the soft-start procedure is not enabled.
