7 Summary

Two typical applications of operating the two channels of LM5171 independently are introduced,

• Two independent CC/CV chargers.
• A boost converter cascaded by a buck converter.

The circuit differences between the two channels of LM5171 are shown. The missing features of CH2 for a complete bidirectional converter are summarized. The design requirements of the external circuits are analyzed. Detailed block diagrams of the external circuit are shown, and some design examples are given.
