Application Diagram TLE8366EV

Note: This is a very simplified example of an application circuit. The function must be verified in the real application

The output voltage of the TLE8366EV can be programmed by a voltage divider connected to the feedback pin FB.

The divider cross current should be 300 µA at minimum, therefore the maximum
