7.2.1 Isolated Flyback CC/CV Feedback

As shown in Figure 7-1, the TL103Wx is often used alongside an opto-coupler/opto-emulator to provide feedback to an isolated flyback. Utilizing the TL103Wx in this way allows for both an accurate and cost-optimized battery charger design that can achieve a stable CC/CV (Constant Current/Constant Voltage) charging profile. In this example, a simplified design procedure will be discussed. Additional details can be found in Designing CC-CV Feedback Circuits With the TL103WB.
