UC3854 – High Power Factor Preregulator IC – DIP-16 Package
The UC1854 provides active-power factor correction for power systems that otherwise would draw non-sinusoidal current from sinusoidal power lines. This device implements all the control functions necessary to build a power supply capable of optimally using available power-line current while minimizing line current distortion. To do this, the UC1854 contains a voltage amplifier, an analog multiplier and divider, a current amplifier, and a fixed-frequency PWM. Tags, UC3854AN, UC3854, UC3854N, UC3854-N.
