Hi,

My customer is design the LIPS power, in which there is a standby power of 5Vsb. How to meet the requirement of input power less than 0.5W at 5Vb/70mA?

After tested with UCC28610EVM, the power is 0.6W around, it can not meet the power saving requirement of 0.5W. Could you suggest that how to meet the power saving spec!
