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.

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 VIN Range: 4.5V to 38V (40V Abs Max) and Operates Down to 2.5V After Start-Up
  • Output Voltage Up to 60V n ±1% 1.200V Reference Voltage
  • RSENSE or Inductor DCR Current Sensing
  • 100% Duty Cycle Capability for Synchronous MOSFET
  • Low Quiescent Current: 135μA
  • Phase-Lockable Frequency (75kHz to 850kHz)
  • Programmable Fixed Frequency (50kHz to 900kHz)
  • Power Good Output Voltage Monitor
