DCPA10515D: DCPA10515DP

Part Number: DCPA10515D

Hello,

On the same board, 17 DCPA10515DP type converters will be used.
When we power up 17 converters at once, won't we have startup issues?
400mA for 2ms is the irush current, or 6.8A for 17 converters. (The datasheet's chapter 8.2.4)
I appreciate your assistance.

Best regards

YD

    Hi YD,

    Thank you for posting.  It can be a concern, although the 17 converters would hardly be all perfectly synchronized during startup.  If you system cannot handle such peak inrush, you may consider to employ a hotswap device in the front end to limit the inrush, or find a way to power up these in a sequence. 

    Thanks,

    Youhao
