DESCRIPTION

The TK83854 family of integrated circuits provide active power factor correction for power systems that otherwise would draw non-sinusoidal current from sinusoidal power lines. These parts implement all the control functions necessary to build a power supply preregulator capable of optimally using available power-line current while minimizing line-current distortion. To do this, the TK83854 contains a voltage amplifier, a precision analog multiplier/divider, a current amplifier, and a fixed-frequency PWM. In addition, the TK83854 contains a power MOSFET gate driver, 7.5 V reference, line anticipator, load-enable comparator, low supply detector, and overcurrent comparator.

FEATURES

■ Control Boost PWM to 0.99 Power Factor

■ Limit Line Current Distortion to < 5

■ Worldwide Operation without Switches

■ Feed-Forward Line Regulation

■ Low Noise Sensitivity

■ Pin Compatible with UC2854, and UC3854 (Licensed Source)

■ Low Start-Up Supply Current

■ Fixed-Frequency PWM Drive

■ Low-Offset Analog Multiplier/Divider

■ 1 Amp Totem-Pole Gate Driver

■ Precision Voltage Reference
