- Limiting DDR Termination Regulators’ Inrush CurrentPDF, 772 Kb, Datei veröffentlicht: 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 - AN-1254 DDR-SDRAM Termination Simplified Using a Linear Regulator (Rev.
