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
For the desired output voltage level
Add a 0.5 nF capacitor close to FB pin.
