ADJUSTABLE STEP-UP / STEP-DOWN VOLTAGE REGULATOR LM2577 + LM2596 in Bangladesh.
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. CityTechBD
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. CityTechBD
