LTC3788 Datasheet Dual Output Synchronous Boost Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3788 2-Phase, Dual Output Synchronous Boost Controller.

General Description

The LTC®3788 is a high performance 2-phase dual synchronous boost converter controller that drives all N-channel power MOSFETs.

Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing the LTC3788 to be used in high power boost applications.

A constant-frequency current mode architecture allows a phase-lockable frequency of up to 850kHz.

Key Features

  • n Synchronous Operation for Highest Efficiency and Reduced Heat Dissipation n Wide Input Range: 4.5V to 38V (40V Abs Max) and Operates Down to 2.5V After Start-Up n Output Voltages Up to 60V n ±1% 1.2V Reference Voltage n RSENSE or Inductor DCR Current Sensing n 100% Duty Cycle Capability for Synchronous MOSFET n Low Quiescent Current: 125µA n Phase-Lockable Frequency (75kHz to 850kHz) n Programmable Fixed Frequency (50kHz to 900kHz) n Selectable Current Limit n Adjustable Output Voltage Soft-St.
