LTC3787 - PolyPhase Synchronous Boost Controller
LTC3787 . PolyPhase Synchronous Boost Controller FEATURES DESCRIPTION. n 2-Phase Operation Reduces Required Input and The LTC 3787 is a high performance PolyPhase single Output Capacitance and Power Supply Induced Noise output Synchronous Boost converter Controller that drives n Synchronous Operation for Highest Efficiency and two N-channel power MOSFET stages out-of-phase. Reduced Heat Dissipation Multiphase operation reduces input and output capacitor n Wide VIN Range: to 38V (40V Abs Max) and requirements and allows the use of smaller inductors than Operates Down to After Start-Up the single-phase equivalent. Synchronous rectification in- n Output Voltage Up to 60V creases efficiency, reduces power losses and eases thermal n 1% Reference Voltage requirements, enabling high power Boost applications. n RSENSE or Inductor DCR Current Sensing n A to 38V input supply range encompasses a wide 100% Duty Cycle Capability for Synchronous MOSFET.
