This board contains LM2577S and LM2596 voltage regulator ICs and this is a buck-boost voltage converter that you can set the output voltage via the trimpot on the board. You can both increase or reduce the input voltage as output. The regulator can pass through current up to 4A on itself.
The board's input voltage can be between 4V and 35V; it's output voltage can be adjusted between 1.25V and 25V.
One of the regulators on the board is a step-down converter and the other is step-up converter. You can set the output voltage through the trimpot, after giving an input. If you want the voltage is reduced, the step-down converter steps in to reduce input. In the other case, step-up converter steps in. In addition there are 2 more trimpots on the board. One for limiting the output current and the other for revolving light current. Besides it is being used as DC-DC voltage regulator, it is also used as a LED driver or a solar regulator.

- Buck-Boost Regulator Board
- Contains both LM2577S and LM2596 Voltage Regulator ICs on it.
- Can be used as a LED driver or a solar regulator.
- Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
- Indicator: constant current Indicator Red, Charging indicator Red, Full charge indicator Blue.
- Output short circuit protection: Yes, constant current (constant current setting values)
- Input Reverse Polarity Protection: None (Please Series diode at the input port.)
- Revolving light current: constant current value * (1% -100%), Revolving light current value Linkage with the constant current value, such as the constant current value is 3A, Revolving light current is set to constant current of 0.1 times (0.1 * 3A = 0.3A) when adjusted to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times
- Operating Temperature: Industrial (-40°c to +85°c) (if ambient temperature exceeds 40 °c, please lower power use, or to enhance heat dissipation)
- Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency
- if use Solar as power supply, please make sure the input power is 1.1 times than the output power.
