Hi Team,

How can I calculate the compensation parameters (R, C, and C values)?

Given:

Input voltage $V_{in}$ : 9–36 V
Output voltage $V_{out}$ : 28 V
Output current: 1.5 A
Switching frequency: 420khz

Hi Thirupathi,

thank you for using the E2E forum.

Best is to use the quickstart calculator for that:

Thank you for sharing the link. However, it does not display the typical value for $V_{CS}$ , and I was unable to locate this information in the datasheet as well.
