  • Use A DSC For Digital Current-Mode Control

    By Bryan Kris, November 16, 2006

    Given: V = L di/dt I(t) = I(t0) + 1/L × ∫ V(t) dt Rearrange: (L/V) × (I(t) - I(t0)) = dt Using the formula: PWM on-time = (L/V) × 2 × (IDESIRED - ISTART) For most applications, the input voltage can't ch

  • Digital Current-Mode Control Challenges Analog Counterparts

    By Bryan Kris, November 16, 2006

    Digital control of switch-mode power supplies (SMPSs) is becoming practical thanks to the evolution of low-cost, high-performance devices with peripherals designed for power-conversion applications. Also, current-mode control is challenging voltage-mode
