FEATURES Controls Boost Preregulator to Near-Unity
Power Factor 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 150-µA Typical Start-Up Current Low-Power BiCMOS Operation 10.8-V to 17-V Operation Programmable Output Voltage (Tracking
Boost Topology)
DESCRIPTIONThe 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.
Designed in T exas 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.
The UCC3819A allows the output voltage to be
programmed by bringing out the error amplifier
noninverting input.
