DESCRIPTION
The L6462A is a control IC for Transition Mode (TM) Boost PFC converters, suitable for building cost-sensitive, energy-efficient solutions. It embeds a special implementation of current-mode control that enables wide-range mains operation with low THD over a broad load range with no need for input voltage sensing and without a classical analog multiplier.
