25V, 600 mA buck-boost DC/DC with 1.6 µA Iq

LTC3130 and LTC3130-1 are synchronous current mode buck-boost converters that deliver up to 600 mA of continuous output current from a wide variety of input sources, including single- or multiple-cell batteries as well as solar panels and supercapacitors. By Graham Prophet @ edn-europe.com

Their 2.4V to 25V input voltage range and 1V to 25V output range (LTC3130 is adjustable) provide a regulated output with inputs above, below or equal to the output. User selectable Burst Mode operation lowers quiescent current to 1.6 µA (1.2 µA at no load) improving light load efficiency and extending battery run time. The proprietary buck-boost topology incorporated in the LTC3130/-1 provides low noise, jitter-free switching through all operating modes, for RF and precision analogue applications that are sensitive to power supply noise.
