Abstract

A flyback light-emitting diode (LED) driver (1) for stabilizing an average current (I<avg>) flowing through at least one LED lamp (2-i), said flyback LED driver (1) comprising a peak current correction control circuit (17) adapted to compensate dynamically a variation of an operation time period (T) of said flyback LED driver (1) by adjusting a peak current (I<peak>) of a coil (5) connected in parallel with at least one LED lamp (2-i) in response to the changing operation time period (T).
