LN2542 - 85~265V AC Input LED Constant Current Driver
The LN2542 is a high voltage buck control IC for constant LED current regulation.
The LN2542 operates constant off-time mode.
It allow efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 450VDC or 110VAC/220VAC.
The LN2542 includes a PWM dimming input that c
