MP2330 Output Voltage Ripple

Hello, when I provide 12V input to my MP2330 Buck converter to power a series of LEDs, the output voltage at around 5 V starts to ripple like the image shows and the LEDs start to flicker. Should I choose a different inductor value or is it a problem with the output capacitance?

Hello,

Apologies for the delayed response. Would you mind providing more details?
What is the load current? Does this happen periodically? Did you look at the switch node and inductor current waveform?

Best Regards,
Yu
