Product Summary
The L6562AD is a current-mode PFC controller operating in Transition Mode (TM). Coming with the same pin-out as its predecessors L6561 and L6562, the L6562AD offers improved performance. 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 (1.4% @TJ = 25°C) internal voltage reference. The L6562AD features extremely low consumption (60μA max. before start-up and <5 mA operating) and includes a disable function suitable for IC remote ON/OFF, which makes it easier to comply with energy saving requirements (Blue Angel, EnergyStar, Energy2000, etc.). An effective two-step OVP enables to safely handle overvoltages either occurring at start-up or resulting from load disconnection.
