InnoSwitch-CE - High Frequency Ripple on DC Output - 5V 15W SMPS
I am designing a 15W 5V SMPS Board for a universal line voltage input (85V-265V). Most of the design works well but I am seeing a lot of High-Frequency Ripple on the Output of the SMPS PCB. See the attached Schematic and Waveforms for the measurements and design.
Please can someone review and advise what I could do to reduce / eliminate this HF Ripple component from the DC output? It increases in amplitude with increase in Line Voltage input at the maximum power output level (3A / 15W).
