    Hello,

    From our previous communications, I assume that you are talking about the Sepic evaluation board.  Is that correct?  Can you please give me the specifications that you are trying to design to?  Why are you doing low side current sensing? 

    When you are talking about the PWM frequency, are you talking about the PWM dimming frequency or PWM switching frequency?

    Thanks Tuan
