Hi Kura,

I don't understand your question. Is it the tdelay parameter that you ask about?

Chris-san

Thank you for your reply.

I would like to know tdelay equation.

VIN:5V ,Ccp=10uF(In this case, tdelay is 5ms)

Hi Kura,

This is explained in section 7.4.4 and shown in Figure 27-30.

The time can be simplified to basically just I = C dv/dt. But the 50 mA is not a precise 50 mA and so there will be some difference in the exact timing.

How is this important for your application?
