Hi all,
我們使用 We use TLV62585 for 3.3V 轉 convert to 1.8V應用 application.
SPEC建議值 recommend value of C3是 is 22PF,想請問是否可以使用 I'd like to ask if it can be 18PF?
謝謝 Thank you

Hello Eva,
Thank you for using E2E,

To improve the load transient response, a 22pF is good for 1.8V output application, but you can also use 18pF. It should not be a problem.
Thank you & regards,
Moheddin.
Hi Moheddin,
If we utilize the TLV62585 for a 5V to 0.9V conversion application with a load ranging from 0.9A to 1.2A, I would like to inquire whether C3 can be set to 18pF. Alternatively, is there a recommended value for C3?
Thank you
Hello Eva,
The feedforward (Cff) will affect the step load performance. A higher Cff will result to lower overshoot/undershoot, but extended the recovery time. And to calculate for the Cff, please refer to the formula below.
t = Cff * (RFB_down)
t: 2200ns
Cff: feedforward capacitor
