ADVANCED HIGH-POWER FACTOR PREREGULATOR

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 V_AC

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 (V_RMSsquarer), input supply voltage

clamp, and over current comparator round out the lilst

of feataures.

•

V_REFGOOD Comparator

Faster and Improved Accuracy ENABLE

Comparator

Available in the 16-pin N (PDIP), DW (SOIC Wide),

and J (CDIP) and 20-pin Q (PLCC) package. See
