Datasheet Summary
SGM3128 3-Channel Low Dropout Low Side White LED Driver
GENERAL DESCRIPTION
The SGM3128 driver provides a simple solution for a matched current source for mon Anode LED configuration.
The SGM3128 can drive three LEDs or one LED at three times the current. The factory preset current value is 30mA per channel.
The SGM3128 requires only a 50mV dropout voltage at a 30mA load on each output to match the LED brightness.
The SGM3128 is available in Green SOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
