Joey, hello and thank you for your interest in Texas Instruments TI Designs. Your question will be forwarded to our Power Design Services team that originally designed it back in 2015. Please allow some time for a response (perhaps as late as early next week) as many of our Power Design Services team is on holiday break until next Tuesday, January 2nd.

Best Regards,

Joey,

Do you need output ripple information at a specific current or at no load?

Do you have a specific requirement at a specific load?

"Low load" is somewhat ambiguous.

Regards
John

Hello Joey,

In the test report, section 4, page 6, it is reported the screenshot of the output voltage, measured at no load (Iout = 0A), while the previous image shows the ripple during burst mode (@ Iout = 100mA).

Thanks and best regards,

Roberto
