STMicroelectronics L6564T
The L6564T is a current-mode PFC controller operating in transition mode (TM) and represents the compact version of the L6563S as it embeds the same driver, reference and control stages in a very compact 10-pin SO package. The highly linear multiplier, along with a special correction circuit that reduces crossover distortion of the mains current, allows wide-range-mains operation with an extremely low THD even over a large load range. The output voltage is controlled by means of a voltage-mode error amplifier and an accurate (1% @TJ = 25 °C) internal voltage reference.| Part No. | L6564T |
