LTC3787EUFD#TRPBF

LTC3787 is a high performance PolyPhase® single output synchronous boost converter controller that 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 than the single-phase equivalent. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, enabling high power boost applications. It is widely used in application such as industrial, automotive, medical, military etc.
