TK83854 Datasheet (TOKO) - HIGH POWER FACTOR PREREGULATOR

TK83854, HIGH POWER FACTOR PREREGULATOR

The TK83854 family of integrated circuits provide active power factor correction for power systems that otherwise would draw non-sinusoidal current from sinusoidal power lines.

These parts implement all the control functions necessary to build a power supply preregulator capable of optimally using a
