1 - Value of R10 ? ( value of R7, R8 and R9 from pi xls designer )
2 - Number of turns of bias ?
thanks

1. You may use 47k for R10 (see RD-257 for reference).
2. For LNK-PH Buck PIXLS, bias may not be necessary if you use the circuit as per RD-257, thus the option for number of turns for bias is not included. Nevertheless, if you want to use bias supply instead of using R7-R9 circuit, then use the equation Nb= Vb*Np/ Vo
