LTC3787 Datasheet Polyphase Synchronous Boost Controller

Manufacturer: Linear Technology Corporation

Overview: LTC3787 PolyPhase Synchronous Boost Controller.

General 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.

Key Features

  • n 2-Phase Operation Reduces Required Input and Output Capacitance and Power Supply Induced Noise n Synchronous Operation for Highest Efficiency and Reduced Heat Dissipation n Wide VIN Range: 4.5V to 38V (40V Abs Max) and Operates Down to 2.5V After Start-Up n Output Voltage Up to 60V n ±1% 1.200V Reference Voltage n RSENSE or Inductor DCR Current Sensing n 100% Duty Cycle Capability for Synchronous MOSFET n Low Quiescent Current: 135μA n Phase-Lockable Frequency (75kHz to 850kHz) n Programmable.
