Buck-Boost click™ features LTC3129-1, a buck-boost DC/DC conversion integrated circuit from Linear Technology®. The click supports a wide input voltage range and can output eight discrete regulated output voltage levels, selectable by the digital output voltage selection pins, ranging from 2.5V to 15V. The main features of this converter are its very low noise and low ripple at the output, as well as very high regulating efficiency and low quiescent current. Those features make the Buck-Boost click a perfect solution for the regulators and post-regulators for harvested energy, solar panel post-regulators/chargers, rechargeable battery output voltage regulators, wireless low noise applications and similar.
