LM5069: Remove Insertion Delay

Matthew Bavier

Part Number: LM5069

Hi,

I was wondering if it is possible to have the insertion delay on this device be 0? If not is there an alternate part like this but without the insertion delay?

Thank you,

Hi Avishek,

The current limit is being set to 1.9A. Does this insertion delay occur only on start-up or does it happen if you disable and enable it via UVLO after start-up?

Also to confirm, the inrush current limit is set by Rsense, correct?

Thank you,

Matthew Bavier

Hi Matthew,

The insertion delay only occurs when VIN is applied, doesn't happen if you disable and enable it via UVLO after start-up.

The inrush current limit is set through RSNS as well as RILIM resistances.
