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 A at minimum, therefore the maximum
R
2 calculates:
R
2 VFB / IR2
-->
R
2 ≤ 0.6V / 300 A = 2 k
For the desired output voltage level
V
CC, R1 calculates then (neglecting the small FB input current):
Add a 0.5 nF capacitor close to FB pin.
