Overview
85~265V AC Input LED Constant Current Driver LN2542 ■ General Description 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 can accept an external control signal with a duty ratio of 0 100% and a frequency of up to a few kilohertz, and the dimming also accept a 0-1.
2V linear input signal.
The RNTC pin can accept a 0-250mV Line Dimming input witch be used for temperature compensation of the LED current.
LN2542 is available by SOP-8 packages.
