UC3854B, UC3854A, Enhanced High Power Factor Preregulator

Enhanced High Power Factor Preregulator UC1854A/B UC2854A/B UC3854A/B .
The UC1854A/B products are pin compatible enhanced versions of the UC1854.

Features

* Controls Boost PWM to Near Unity Power Factor
* Limits Line Current Distortion To

Applications

* reference data refer to Unitrode application notes U-134 and DN-44. MULTIPLY / SQUARE AND DIVIDE The UC1854A/B Multiplier design maintains the same gain constant (K =
* 1), as the UC1854. The relationship between the inputs and output current is given as: IMO = IAC(VAO - 1.5V) / K
* VRM
