LM5069: Would like to calculate the restart time(t_RESTART)

Hi Shunsuke,

Let me check on this.

Hi Kunal,

Thank you for the reply. I am looking forward to your reply.

Hi Rakesh-san,

Thank you for the reply. Is these equeations same with the equations of LM5066I?

May I know if we can use these equations to calculate T_FAULT and T_RESTART of LM5066I?

Best regards,

Shunsuke Yamamoto

There will be slight difference. You can use design calculator on web. It will show restart time calculated value.

Hi Kunal,

Thank you for the reply. We don't have specific MOSFET part number, so it is difficult to estimate t\fault and T_RESTART based on the excel sheet. Could you please kindly check the equation to obtain these values in LM5066I?

Best regards,

Shunsuke Yamamoto

Those timings are independent of fet. Let me show you in calculator.

Download from here.

Enter cap value in highlighted area. Below cell will show fault timer value.

This table at bottom of calculator will show restart timer value.

FET value does not matter.
