Texas Instruments UCC3818 BiCMOS Power Factor Pregulator IC (16 Pin) 35 A High noise margins and strong

High noise margins and strong immunity to isolation-mode transients are provided by this modulation

The UCC3895 is a phase shift PWM (pulse-width modulation) controller that implements control of a full-bridge power stage by phase shifting the switching of one half-bridge with respect to the other

Texas Instruments UCC3818 BiCMOS Power Factor Pregulator IC (16 Pin) 35 A High noise margins and strongThe UCC3818 functions as an active power factor corrected pre regulator. The controller achieves a 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. It is designed by Texas Instruments using the BiCMOS technology. The BiCMOS technology combines the strengths of two different process technologies
