TIDA-00200 proposes an interleaved flyback topology for battery charger applications that require an output power level of ~200 W with a minimized bill of material. Besides the actual electronic components, the efforts for cooling are a major contributor to the overall design cost. By taking advantage of the LM5032 high voltage dual interleaved current mode controller, the design accomplishes great efficiency of 90% at full load and spreads out the heat for reduced cooling efforts. A fan is typically not needed. The need for smaller form factor heat sinks provides additional design flexibility.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
