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.
The TK83854 family uses average current-mode control to
accomplish fixed-frequency current control with stability
and low distortion. Unlike peak current-mode control,
average current control accurately maintains sinusoidal
line current without slope compensation.
FEATURES (CONT.)
■ Low Start-Up Supply Current
■ Fixed-Frequency PWM Drive
■ Low-Offset Analog Multiplier/Divider
■ 1 Amp Totem-Pole Gate Driver
■ Precision Voltage Reference
circuitry that supplies power to this device, the TK83854
family features low start-up supply current.
These devices are available in 16-pin plastic dual in-line
(DIP) and 16-pin surface mount (SOP) packages.
