STMicroelectronics L6562A
The L6562A is a current-mode PFC controller operating in Transition Mode (TM). The highly linear multiplier includes a special circuit, able to reduce AC input current distortion, that 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. | L6562A |
