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.

The transformer bias winding is used to sense output voltage for regulation, and for low-loss input voltage sensing. Advanced sampling techniques allow CCM operation, and deliver excellent output voltage regulation performance for opto-coupler-less designs at power levels of 100 W and above.

A high-voltage current source enables fast and efficient start-up. Advanced light-load modes are deployed to reduce both controller and system power consumption at no load and light load. These modes enable potential system designs to meet 30-mW no-load power for power designs up to 30 W nominal, 60 W peak.

The device has been designed for ease-of-use and incorporates many features to enable a wide range of designs. Extensive protection features are included to simplify system design.

See the Device Comparison Table for details.
