Hello Team,

I would need your help to review the schematics and advice to make changes to the circuit for the below parameters -

Vin - 2.7V - 24V, Vout - 5V Iout - 2.4A in CC mode.

The schematics attached is referenced from TPS55288EVM-045.

Thanks.

Regards,

Hi Subhendu,

I found many mistakes on your schematic. Please check the attached review result.

By the way, what is the Vin/Vo/Io? we need to calculate the compensation network depend on the real demands.

Thanks，

Please strictly follow the TPS55288 EVM schematic.

For the Cout, you can use 2X10uF cap +100uF EL cap at the output side. Based on this output cap, please change the compensation network: Rcomp=20k; Ccomp=10nF, Cp=100pF.

And please correct the error in your schematic.
