LM2577 chip module uses high-quality, high efficiency, heat a small, no increase in the case of the radiator can go to 15W, plus the radiator can be achieved after the 20W of output power.
This module is adjustable boost module, you can adjust the module above the sinking blue adjustable resistor to change the output voltage. The maximum output voltage is 35V.
Modules indicated above IN-(negative input), IN + (positive input), OUT-(negative output), OUT + (positive output)must be connected correctly, otherwise it may cause damage to the module.
Do not exceed the rated output power of this module, for example the module (20W) can not be used to supply laptop (90W)use.
This module has no output short circuit protection, output short circuit if prolonged, may result in damage to the module.
