Description
UCC3818DG4 Description All of the functions required for active power factor-corrected preregulators are provided by the UCC3818DG4. By shaping the AC input line current waveform to correspond to the AC input line voltage, the controller achieves a near-unity power factor. Average current mode control keeps sinusoidal line current stable and low in distortion. This device is designed in Texas Instruments' BiCMOS process and offers new features such as lower start-up current and lower power dissipation. UCC3818DG4
