About the transfer function for the closed-loop system in AN5496

[diverger]

Hi, I'm reading the AN5496 - Rev 3. I'm confused by equation (6) and (7). If all they are the transfer function of the closed-loop system, why there are different?

Thanks.

Hello @diverger​,

Thank you for your contribution on ST Community,

I will check internally and get back to you soon.

The explanation may not be clear.

Thanks for highlighting it!

Hello @diverger​, 

The transfer function is not synthesized in terms of Hp(s), Hc(s) and PWM. It would be better to explain the closed loop transfer explicitly.
