IS32LT3174 - LINEAR LED DRIVER

General Description

The IS32LT3174 is a linear programmable current regulator consisting of one output channel capable of up to 200mA.

Key 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 the channel, while a separate, single resistor programs the fade in and fade out rate for channel. 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 curren.
