The MikroElektronika Buck-Boost 2 click board is an advanced DC-DC step-down/step-up regulator (buck/boost) click 2 board, which can provide regulated 5V on its output, regardless of the input voltage. The input voltage can range from 2.7V up to 40V. The click board™ provides ultra-low noise and ripple-free regulated output with transparent switching from buck to boost mode depending on the input voltage, which produces no discontinuities or switching artefacts such as transients or sub-harmonic switching. Selectable switching mode allows optimal power consumption and high power efficiency for both, lighter and heavier loads.
