Hi Avishek,

Recommended Operating Conditions for EN pin max is 7V.

As your input voltage is 28V, you can use R577 = 51k and R578 = 5k for Enabling the IC.

Schematic seems accurate assuming the Inductor you are using L81 = 22uH.

Best Regards,

Usha.

Hi Usha,

1)Here we are converting 28V to 24V , i wanted to know if 2A is enough for the conversion.

2) Also, I Request you to provide graphs of efficiency and load regulation with input 28V.
