Description
The L6562AT is a current-mode PFC controller operating in transition mode (TM). Coming
with the same pin-out as its predecessors L6561 and L6562, it 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% @T
The device features extremely low consumption (60 µA max. before start-up and < 5.5 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 over-voltages either occurring at start-
up or resulting from load disconnection.
The totem-pole output stage, capable of 600 mA source and 800 mA sink current, is suitable
to drive high current MOSFETs or IGBTs. This, combined with the other features and the
possibility to operate with the proprietary fixed-off-time control, makes the device an
excellent low-cost solution for EN61000-3-2 compliant SMPS in excess of 350 W.
