应用须知

  • Limiting DDR Termination Regulators’ Inrush Current
    PDF, 772 Kb, 档案已发布: Aug 23, 2016
    The output voltage of DDR termination regulators tends to rise quickly after their VDDQ line is enabled. Most DDR terminators are specifically designed for fast start-up. They also require bulky output capacitors for a stable output voltage. This often results in a significant inrush current from DDR terminator voltage supply to charge the output capacitors and to provide curre
