9.2.2.5.3 Recommended Transformers
Depending on the application, use the minimum configuration in Figure 9-7 or standard configuration in Figure 9-8.
Figure 9-7 Unregulated Output for Low-Current Loads With Wide Supply Range
Figure 9-8 Regulated Output for Stable Supplies and High Current LoadsThe Wurth Electronics Midcom isolation transformers in Table 9-3 are optimized designs for the device, 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.
