Hi~
Customer uses LM3410X for 7" backlight application.
Based on datasheet(Fig.4), it looks cover up to 20kHz dimming frequency, but actually, customer board can't dim operation with that frequency.
When change PWM dim freq to 300Hz, looks pwm dimming operation well but it has large input ripple current, so now trying to change.
Please, let me know available PWM dimming freq range.(Fig.4 validation)
Thanks.
