The LTC3784 is a high power multiphase single output synchronous boost converter controller. This device replaces rectifying boost diodes with high efficiency N-channel MOSFETs and drives two N-channel power MOSFET stages out-of-phase. Multiphase operation reduces input and output capacitor requirements and allows the use of smaller inductors versus the single-phase equivalent. Synchronous rectification increases efficiency, reduces power losses and eases thermal design, thereby greatly simplifying high power boost applications.
