DESCRIPTION
The LTC®3787 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

FEATURES
■ 2-Phase Operation Reduces Required Input and
   Output Capacitance and Power Supply Induced Noise
