Analog Ramp Generator with Slope Compensation


  • Analog ramp generator (with slope compensation) for Switch Mode Power Supplies (SMPS)
  • Creates independent rising and/or falling voltage ramps
  • Multiple interconnects for closed loop control
  • Multiple output modes
    • Examples: slope, ramp, triangle
  • Intelligent control of integrated analog feedback loop


  • BOM cost reduction
  • Simplifies SMPS design
  • Core-independent operation
  • Operation while in low-power sleep
