Texas Instruments UCC2863x targets high-performance flyback converters on the primary side. The ability to work in both CCM and DCM makes it ideal for applications with a wide range of performance. The peak power mode allows transient peak power up to 200% of the rated power, with a peak increase of only 25%, thereby maximizing transformer utilization.
&;
The transformer's polarized winding is used to detect the output voltage to regulate and detect the low loss of the input voltage. Advanced sensing technology enables CCM operation and provides excellent output voltage regulation for non-optocoupler designs with powers greater than 100W.
&;
&;
The device is designed to be easy to use and has many features for multiple designs. Integrated advanced protection features to simplify system design.
