TPS610981: No-load high ripples

Tool/software:

Hi, 

I am using TPS610981DSER part. 

I am having this schematic - 

 DC_DC#1.pdf

I removed R13 so the other parts won't interfere with the testing, and probed TP26. 

at TP26 i see this voltage when there no load connected to the DC/DC - 

my Input voltage is 3V0. 

is this a normal behavior of the device ? 

can you help me smooth that output ? 

when I put 20mA load on the output, it smooths the output. TP26 with 20mA load -

thanks, 

Michael
