FEATURES  
DESCRIPTION  
Controls Boost PWM to Near-Unity Power  
Factor  
The UC3854A/B products are pin compatible  
enhanced versions of the UC3854. Like the UC3854,  
these products provide all of the functions necessary  
for active power factor corrected preregulators. The  
controller achieves near unity power factor by  
shaping the ac input line current waveform to  
correspond to the ac input line voltage. To do this the  
UC3854A/B uses average current mode control.  
Average current mode control maintains stable, low  
distortion sinusoidal line current without the need for  
slope compensation, unlike peak current mode  
control.  
Limits Line Current Distortion To <3%  
World-Wide Operation Without Switches  
Accurate Power Limiting  
Fixed-Frequency Average Current-Mode  
Control  
High Bandwidth (5 MHz), Low-Offset Current  
Amplifier  
Integrated Current- and Voltage-Amplifier  
Output Clamps  
Multiplier Improvements: Linearity, 500 mV VAC  
Offset (Eliminates External Resistor), 0 V to  
5 V Multout Common-Mode Range  
A 1%, 7.5-V reference, fixed frequency oscillator,  
PWM, voltage amplifierwith soft-start, line voltage  
feedforward (VRMS squarer), input supply voltage  
clamp, and over current comparator round out the lilst  
of feataures.

Available in the 16-pin N (PDIP), DW (SOIC Wide),  
and J (CDIP) and 20-pin Q (PLCC) package. See  
Ordering Information table for availability by  
temperature range.
