A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (load) On the other hand A boost converter is a DC to DC converter with an output voltage greater than the source voltage. Auto start voltage will be pulled down to 7V or less, and the engine will at high speed when the voltage up to 15V or higher. It is hard to work for 12V electrical equipment, this automatic buck-boost module can solve this problem, regardless of the input voltage is 5V or 12V or 32V, the output can be stabilized at 12V. Built-in 4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)High switching frequency 400KHz, the ripple is smaller, dimension is smaller. (LM2577 frequency only 50KHz)
Car regulator, solar photovoltaic, wind power and other applications of voltage instability.
