UCC2863x High Power Flyback Controllers

Texas Instruments UCC2863x High Power Flyback Controllers target high-power, primary-side regulated flyback converters. The ability to operate in both CCM and DCM makes the device suitable for applications with a wide power range. The peak power mode allows transient peak power delivery up to 200% of the 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 low-loss input voltage sensing. Advanced sampling techniques allow CCM operation and deliver excellent output voltage regulation performance for optocoupler-less designs at power levels of 100W and above.
