IS31LT3910 Datasheet | ISSI

UNIVERSAL HIGH BRIGHTNESS LED DRIVER WITH TEMPERATURE PENSATION GENERAL DESCRIPTION The IS31LT3910 is a peak current mode control LED driver IC. The IS31LT3910 operates in constant off-time mode. It allows efficient operation of High Brightness (HB) LEDs with voltage sources ranging from 8VDC to 450DC or 110VAC/220VAC. The IS31LT3910 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 240mV linear dimming input which can be used both for linear dimming and temperature pensation of the LED current. The IS31LT3910 is ideally suited for buck LED drivers.
