IS32LT3143 - Lumissil

IS32LT3143 3-CHANNEL LINEAR LED DRIVER

The IS32LT3143 device is a linear programmable LED driver consisting of three current source output channels capable of up to 150mA each. It supports individual PWM dimming control to each channel. A single resistor sets the maximum current level for all channels. The output channels can be combined to provide a higher current drive capability up to maximum .

Features

• Wide input voltage range: 5V~40V
