The UCC28070 is an advanced power factor
correction device that integrates two pulse-width

substantial reduction in the input and output ripple
currents, and the conducted-EMI filtering becomes
easier and less expensive. A significantly improved

matched average current mode control in both PWM
outputs while maintaining a stable, low-distortion
sinusoidal input line current.
The UCC28070 contains multiple innovations
including current synthesis and quantized voltage
feed-forward to promote performance enhancements
in PF, efficiency, THD, and transient response.
Features including frequency dithering, clock
synchronization, and slew rate enhancement further
expand the potential performance enhancements.
The UCC28070 also contains a variety of protection
features including output over-voltage detection,
programmable peak-current limit, under-voltage
lockout, and open-loop protection.
