description  
The UCCx817/18 family provides all the functions necessary for active power factor corrected preregulators.  
The controller achieves near unity power factor by shaping the ac input line current waveform to correspond  
to that of the ac input line voltage. Average current mode control maintains stable, low distortion sinusoidal line  
current.  
Designed in Texas Instrument’s BiCMOS process, the UCC2817/UCC2818 offers new features such as lower  
start-up current, lower power dissipation, overvoltage protection, a shunt UVLO detect circuitry, a leading-edge  
modulation technique to reduce ripple current in the bulk capacitor and an improved, low-offset ( 2 mV) current  
amplifier to reduce distortion at light load conditions.
