UC1854B, UC1854A, Enhanced High Power Factor Preregulator
The UC1854A/B products are pin compatible enhanced versions of the UC1854.
Like the UC1854, 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 correspo
UC1854B Features
* Controls Boost PWM to Near Unity Power Factor
* Limits Line Current Distortion To
