Product Overview

The LT1683EG#PBF is a Switching Regulator Controller designed to lower conducted and radiated electromagnetic interference (EMI). Ultralow noise and EMI are achieved by controlling the voltage and current slew rates of external N-channel MOSFET switches. Current and voltage slew rates can be independently set to optimize harmonic content of the switching waveforms vs efficiency. The LT1683 can reduce high frequency harmonic power by as much as 40dB with only minor losses in efficiency. It utilizes a dual output (push-pull) current-mode architecture optimized for low noise topologies. The IC includes gate drivers and all necessary oscillator, control and protection circuitry. Unique error amp circuitry can regulate both positive and negative voltages. The oscillator may be synchronized to an external clock for more accurate placement of switching harmonics.
  • Greatly reduced conducted and radiated EMI
  • Low switching harmonic content
  • Independent control of output switch voltage and current slew rates
  • Greatly reduced need for external filters
  • Dual N-channel MOSFET drivers
  • Easily synchronized to external clock
  • Regulates positive and negative voltages
  • Easier layout than with conventional switchers
