General Description

The UCC2863x targets high-power, primary-side regulated flyback converters.

The ability to operate in both CCM and DCM make the device suitable for applications with a wide power range.

The peak power mode allows transient peak power delivery up to 200% of nominal rating, with only a 25% peak current increase, maximizing transformer utilization.
