LT8349 Overview
The LT8349 is a 2-phase single output synchronous boost converter that drives two internal N-Channel power MOSFET stages out-of-phase. Multiphase operation reduces input and output capacitor requirements and allows the use of smaller inductors than the single-phase equivalent. Synchronous rectification increases efficiency, reduces power losses, and eases thermal requirements, enabling high power boost applications.
