SN3910 - Universal High Brightness LED Driver

Download the SN3910 datasheet PDF. This datasheet also covers the SN3910-SI variant, as both devices belong to the same universal high brightness led driver family and are provided as variant models within a single manufacturer datasheet.

Description

The SN3910 is an open loop, current mode, control LED driver IC.

The SN3910 operates constant off-time mode.

It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 450VDC or 110VAC/220VAC.

Features

  • z Switch mode controller for single.

Preliminary SN3910 Universal High Brightness LED Driver General Description The SN3910 is an open loop, current mode, control LED driver IC. The SN3910 operates constant off-time mode. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 450VDC or 110VAC/220VAC. The SN3910 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. It also includes a 0 - 250mV linear dimming input which can be used both for linear dimming and temperature compensation of the LED current. The SN3910 is ideally suited for buck LED drivers.
