LM2596 Voltage converter

Turning clockwise increases, and anticlockwise decreases. Sometimes to activate the converter 20+ turns are needed.

Potentiometer 1 (P1) -Voltage Adjustment.

Potentiometer 2 (P2) -When charging the battery to adjust the current, when to cut off the charging.

For example, if the battery is charged current drawn from Buck Converter will drop significantly, with this potentiometer (P2) cut off current can be adjusted to stop feeding the battery.

Potentiometer 3 (P3) -Current Adjustment.

LEDs are sensitive to excessive current flow. If the current exceeds the manufacturer’s specified limits, it can cause overheating and damage to the LED, leading to reduced lifespan or even complete failure. By limiting the current, you ensure that the LED operates within its safe operating range.
