... L6562A 1 Description The L6562A 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 ...

... L6562A 7.5 Comparison between the L6562A and the L6562 The L6562A is not a direct drop-in replacement of the L6562, even if both have the same pin-out. One function (Disable) has been relocated. Table 2 compares the two devices, i.e. those parameters that may result in different values of the external components. The parameters that have the most significant impact on the design, i ...
