资 源 简 介

The SN3910 is an open loop, current mode, control LEDdriver IC. The SN3910 operates constant off-TIme mode. Itallows efficient operaTIon of High Brightness (HB) LEDsfrom voltage sources ranging from 8VDC up to 450VDC or110VAC/220VAC. The SN3910 includes a PWM dimminginput that can accept an external control signal with a dutyraTIo of 0 - 100% and a frequency of up to a few kilohertz.It also includes a 0 - 250mV linear dimming input whichcan be used both for linear dimming and temperaturecompensaTIon of the LED current.
