TPSM82823A: Confirm frequency response

Part Number: TPSM82823A
Other Parts Discussed in Thread: TPS543C20, TPS543B20, TPS543C20A, TPSM82821A

Tool/software:

Hi team,

My customer would like to confirm frequency response of TPSM82823A. Becuase my customer plans to optimize the value of feedforward capacitor. Pspice for TI and WEBENCH cannot support generating the frequency response. Could you please kindly check if we have the excel sheet which calculates the frequency response? Attached excel file is for TPS543C20.

Shunsuke Yamamoto,

thanks for using E2E.

I checked and such a calculator tool is not available for the TPSM82823A.

The recommended C_FF can be calculated with equation 6 in section 9.2.1.2.2 of the datasheet.

The following application note might be helpful for customized optimization of C_FF and the related measurements: http://www.ti.com/lit/pdf/slva289

Best regards,

Andreas.

Hi Andreas,

Could you please confirm WEBENCH will not support TPSM82821A and TPSM82823A in the future? This information is critaical for my customer to choose DCDC converter.

Best regards,

Shunsuke Yamamoto
