LN2544 Datasheet | natlinear

100V Input Universal High Brightness LED Driver - General Description LN2544 is an open loop, current mode ， built-in NMOSFET, control LED driver IC. The LN2544 operates constant off-time mode. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 100VDC. The LN2544 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 pensation of the LED current. LN2544 is available by SOP-8 packages. - General...
