TPS62826: ripple test result in PSM

Part Number: TPS62826

Hi,

This is for optical module. I found many new optical modules are looking for new 2A+ solution, especially for 56G PAM processor. Customer would like to check the ripple of TPS62826 in power save mode. I don’t think the ripple would became larger in Power Save Mode. I needs test result of comparing PFM to CCM to support me. Could our AE provide test result in below condition? I simulated it in Webench, the ripple is under 10mV in both PFM and PWM mode. It will be better if we could add the ripple measurement result into datasheet.

              Vin=3.3V Vout=1V(other voltage is also fine) Iout is 50mA, 100mA and 2A   

Thanks.
