... Compared to a discrete MOSFET and controller or RCC switching converter solution, the FSQ110 reduces total component count, design size, and weight while increasing efficiency, productivity, and system reliability. These devices provide a basic platform that is well suited for the design of cost-effective flyback converters ...
