50mA Synchronous Buck-Boost DC/DC Converter with Integrated Coulomb Counter Consumes Only 680nA of Quiescent Current

Linear Technology announces the LTC3335, a nanopower high efficiency synchronous buck-boost converter with an onboard precision coulomb counter. It delivers up to 50mA of continuous output current. With only 680nA of quiescent current and programmable peak input currents from 5mA up to 250mA, the device is ideal for a wide variety of low power battery applications. Its 1.8V to 5.5V input range and eight user-selectable outputs between 1.8V and 5V can provide a regulated output supply with input voltage above, below or equal to the output.
