Step up step down DC buck converter module

This unit is a step up step down DC buck converter module. The unit uses an LM2577S for boosting the voltage up and an LM2596S for stepping the voltage down. It has an input range of 3.5 – 28 volts and an output range of 1.25 – 26 volts. Both the input and output is rated at 1 amp stable and 3 amps maximum. (more…)
