LTC3787HGN#TRPBF General Description

The 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.

Key Features

2-Phase Operation Reduces Required Input and Output Capacitance and Power Supply Induced Noise
Synchronous Operation for Highest Efficiency and Reduced Heat Dissipation
Wide V_INRange: 4.5V to 38V (40V Abs Max) and Operates Down to 2.5V After Start-Up
Output Voltage Up to 60V
±1% 1.200V Reference Voltage
R_SENSE or Inductor DCR Current Sensing
100% Duty Cycle Capability for Synchronous MOSFET

Application

Industrial
Automotive
Medical
Military
