Controls Boost Preregulator to Near-Unity  
Power Factor  
The UCC2819A/UCC3819A 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.

World Wide Line Operation  
Over-Voltage Protection  
Accurate Power Limiting  
Average Current Mode Control  
Improved Noise Immunity  
Improved Feed-Forward Line Regulation  
Leading Edge Modulation  
Designed in Texas Instrument’s BiCMOS process,  
the UCC3819A offers new features such as lower  
start-up current, lower power dissipation,  
overvoltage protection, a shunt UVLO detect  
circuitry and a leading-edge modulation technique  
to reduce ripple current in the bulk capacitor.  
150-µA Typical Start-Up Current  
Low-Power BiCMOS Operation  
10.8-V to 17-V Operation  
Programmable Output Voltage (Tracking  
Boost Topology)  
The UCC3819A allows the output voltage to be  
programmed by bringing out the error amplifier  
noninverting input.
