IS32LT3120 LINEAR LED DRIVER

The IS32LT3120 is a linear programmable current regulator consisting of 2 output channels capable of up to 200mA each. Each channel features an ON/OFF input pin to toggle the channel between the OFF condition and the source condition. A single external resistor programs the current level for both of the channels, while a separate, single resistor programs th.

Features

an ON/OFF input pin to toggle the channel between the OFF condition and the source condition. A single external resistor programs the current level for both of the channels, while a separate, single resistor programs the fade in and fade out rate for both channels. The device integrates a 63 steps fade in and fade out algorithm (Gamma correction) which causes the output LED current to gradually ramp up to the full source value after the channel’s control pin is pulsed. The same controller causes the LED current to gradually ramp down to zero if the channel’s input control pin is pulsed while t.
