Product Details
The EVAL-LT8349-BZ evaluation board 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.
The LT8349 converter data sheet provides a complete description of the part that should be read in conjunction with this user guide before operating the evaluation board.
