Tool/software:

Hi, I need TPS62441-Q1 PWM rising, falling time because of EMI simulation. we operate 2.2Mhz

if TI don't have rising, falling time spec, please give me a measuring value.

our company use this product and we are urgent for this

HI,farheen i have another question for this product.

We designed it like above picture.

Can you recommend option for this picture?

I want to choose 1 or 2. 1 is only using 7uF , 2 is good at transient reponse.

could you recommnend 1 or 2 by considering our usecases voltage and current?

In addition, i want to know exact output capacitance value and reason.

Hello Lim,

It depends on what is your transient target. If it is somewhat like 3-5% then I will recommend comp 2.

Thanks,

Farheen

Do you mean if transient current become 3-5% you recommend 2?

then, Can you give a capacitance value each chennels and reason.

we write reason our company document.

Hello Lim,

If you are looking for regulation of around 5% of Vout then you will need higehr capacitance. I can not give you the exact value as this is something you can check on the EVM but using compensation 2 with higher capacitance helps mostly for tigher ouput voltage regulation specs.

Thanks,

Farheen
