Description

 

The UC2854DW  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 UC2854DW contains a voltage amplifier, an analog multiplier/divider,a current amplifier, and a fixed-frequency PWM. In addition, the UC2854DW contains a power MOSFET compatible gate driver, 7.5V reference,line anticipator, load-enable comparator, low-supply detector,and over-current comparator.
