The LM2596S-3.3 basic circuit is used to convert the 6-12v input voltage into a fixed 3.3v output. The output voltage is stable, the current is stable, and the theoretical output can reach 3A.
The 5v fixed output circuit uses LM2596S-5.0 as the voltage step-down voltage regulator chip, which is consistent with the 3.3v circuit principle.
The adjustable output uses the LM2596S-ADJ adjustable buck regulator chip, and the output voltage is changed by adjusting the potentiometer.
