Introduction:
The UC3854N 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 supply power capable of optimally using available power-line current while minimizing line-current distortion.
Some Core Parameters:
SPECIAL FEATURES :
● Control Boost PWM to 0.99 Power Factor
● Limit Line Current Distortion To <5%
● World-Wide Operation Without Switches
● Feed-Forward Line Regulation
● Average Current-Mode Control
● Low Noise Sensitivity
● Low Start-Up Supply Current
● Fixed-Frequency PWM Drive
● Low-Offset Analog Multiplier/Divider
● 1A Totem-Pole Gate Driver
● Precision Voltage Reference
How it Uses in the work:

UC3854N Pinout Connections:
UC3854N Pin Functions:
● Gnd Pin 1: All voltages are measured with re- spect to GND.
● PKLMT Pin 2: peak limit. The threshold for PKLMT is 0.0V.
● CA Out Pin 3: current amplifier output
● ISENSE Pin 4: This is the inverting input to the current amplifier.
● Mult Out Pin 5: multiplier output and current sense plus.
● IAC Pin 6: This input to the analog multiplier is a current.
● VA Out Pin 7: voltage amplifier output
● VRMS Pin 8: RMS line voltage
● REF Pin 9: voltage reference output
● ENA Pin 10: ENA is a logic input that will en- able the PWM output.
● VSENSE Pin 11: voltage amplifier inverting input.
● RSET Pin 12: oscillator charging current and multiplier limit set.
● SS Pin 13 SS will remain at Gnd as long as the IC is disabled or VCC is too low.
● VCC Pin 15: positive supply voltage
