| Market Reality | The L6562A is the transition-mode power-factor-correction controller inside a generation of industrial SMPS front ends, LED drivers and lighting ballasts: an 8-pin part that rides the rectified line, multiplies it into the current reference, watches the zero-crossing for boundary conduction, and folds an over-voltage loop into the feedback pin. Its family history is the substitution content: L6561 and L6562 are NRND, the L6562A is the living part, and the step from 6562 to 6562A changes the multiplier gain, the current-sense clamp and where the Disable function lives - so the same pins hide a different design, and the ST comparison table exists precisely because swaps need the external values re-derived. The drawer hazard is the other 8-pin animal: the UC384x PWM controller shares the shape and nothing else. | The L6562A is the transition-mode power-factor-correction controller inside a generation of industrial SMPS front ends, LED drivers and lighting ballasts: an 8-pin part that rides the rectified line, multiplies it into the current reference, watches the zero-crossing for boundary conduction, and folds an over-voltage loop into the feedback pin.
