Description
UNITRODE / Texas Instruments UC3854DW IC Power Factor Correction Preregulator 1.5mA 118KHz 16-Pin SOIC Tube
The UC1854 provides active power factor correction for power sys- tems that otherwise would draw non-sinusoidal current from sinusoi- dal 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/divider, a current amplifier, and a fixed-frequency PWM. In addition, the UC1854 contains a power MOSFET compatible gate driver, 7.5V ref- erence, line anticipator, load-enable comparator, low-supply detector, and over-current comparator.
