This is the combined buck (step down) and boost (step up) converter based on LM2587 IC. Provide any input voltage between 3V- 35V and you can adjust the output voltage anything between 1.5V- 30V.
It doesn't matter if the input voltage is higher, equal or lower than then output voltage. If the input voltage is lower than the configured output voltage (configured by rotating pot), it will act as a boost converter. And if the input voltage is higher than the configured output voltage, it will act as a buck converter.
Caution: There's no reverse voltage polarity protection at the IN+ and IN- pins.
