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.The LT8349 features Stage Shedding and selectable Burst Mode operation at light load conditions allowing high efficiency over a wide range of load. It features optional spread spectrum frequency modulation (SSFM) to minimize EMI emissions.The LT8349 integrates 8V/6A power switches, operating at a fixed switching frequency programmable between 300kHz and 4MHz and synchronizable to an external clock. The LT8349 features output soft-start and output overvoltage lockout.APPLICATIONSHandheld and Industrial Power Supplies
