The Wurth Electronics Midcom isolation transformers in Table 8-3 are optimized designs for the SN6501, providing high efficiency and small form factor at low-cost.

The 1:1.1 and 1:1.7 turns-ratios are designed for logic applications with wide supply rails and low load currents. These applications operate without LDO, thus achieving further cost-reduction.
