How it works

3 stages · Explore one step at a time

Step 1 / 3

Input and reference

Divide the reference to the intended output level.

Step 2 / 3

Internal control

Compare that level against the sensed regulated output.

Step 3 / 3

Output behavior

Adjust pass current; the sense resistor activates current limiting.
