TPS56C215: Switching frequency on webench

Part Number: TPS56C215

hi, is it possible to select 800kHz or 1.2Mhz in Webench? Seems only 400kHz is possible. Any suggestions? Regards, Andreas

  • It can be changed, I see 400/800k can be changed for all loading, but thermal performance should be considered for 1.2M, so it is limited when higher loading.

    You can follow my picture to make it, if you just swap 400/800, you only use step 2/3/4, if you would use 1.2M, you need change Iout with step1.
