LM5155: Equation(7)

Part Number: LM5155

Hi,

Vslope is calculated by equation(7).

What is this "40mV"?

Is this a specific value of LM5155?

Best Regards,

Kuramochi

    Hi Huramochi,

    Thank you for reaching out.  40mV is the amplitude of the internal slope compensation without external clock sync.  Yes it is a specific value  of the LM5155.   If you sync to a faster frequency, the amplitude of slope compensation will reduce by the factor of fRT/fSYNC.

    Thanks,
