LM3429 Test I have a question during the test.
vin : 12, led : 3.4v x 4 = 13.6, max current 1A
On the DataSheet, I thought that it could be used from 80kHz ~ 119kHz when calculating by the formula (26)
Checked by using actual function generator, there is symptom that current control can not be done according to PWM at 1kHz or more.
When setting the PWM Frequency, please reply if you have any more or need more information.
Test results will be attached.
