Product Details

Demonstration circuit 415 is a SEPIC (step-up or step-down) DC/DC converter featuring the LTC1871 controller. The circuit is capable of providing an output voltage of 12V at 2A from an input voltage of 5V to 15V. External frequency synchronization is provided, as are two modes of operation at light load conditions: Burst Mode^® operation reduces switching losses and maintains high efficiency operation; and continuous mode which provides constant operating frequency with low quiescent current.
