Dear all,
What is the ratio of rippple current to LED current at 0.2A with 4.7uH?
At Table 1, you mention about indictance value (10uH, 15uH and 22uH) and ratio at 0.2A contidion.
How about 4.7uH condition?
Best regards,

Hello Takao,
With a 4.7uH inductor it will be roughly 2x the ripple ratio as with a 10uH inductor. The ripple ratio is directly proportional to inductor value.
