The Slope Compensation (SC) module is designed to provide the necessary slope compensation for fixed-frequency, continuous-current, switching power supplies. Slope compensation is a necessary feature of these power supplies because it prevents instability at duty cycles greater than 50%.

  • Prevents frequency instability
    • Fixed frequency peak current mode (PCM) SMPS
  • Helps stabilize output at duty cycles > 50%
    • Reduces ripple due to limit cycling
  • Programmable slope and frequency generation
  • BOM reduction – compared to external solution
