DESCRIPTION

Controls Boost Preregulator to Near-Unity  
Power Factor  
The UCC3817A and the UCC3818A 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.

Low-Power BiCMOS Operation  
12-V to 17-V Operation  
Designed in Texas Instrument’s BiCMOS process,  
the UCC3817A/UCC3818A 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.
