ANALOG DEVICES EVAL-LT8349-BZ Evaluation Board, LT8349ACBZ, Synchronous Boost Converter

EVAL-LT8349-BZ is an evaluation board that provides a proven design to evaluate the LT8349, 2-phase low IQ, synchronous boost converter. The application circuit is configured to demonstrate optimum performance and component size. Using the board layout example, optimized for conducted, radiated EMI, and thermal performance, will help ensure the designer sees similar performance in their system. The evaluation board is configured to run at 2MHz per phase with a 6V output voltage from an input voltage range of 2.5V to 4.5V and deliver up to 5A load current when VIN is 4.5V. The evaluation board features an adjustable input undervoltage-lockout, external clock synchronization, thermal shutdown, selectable mode of operation and selectable burst mode peak current.
