Overview
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 common 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℃.
APPLICATIONS Wireless Handsets MP3, MP4, and PMP Cellular Phones Portable Communication Devices Digital Cameras, Camcorders PDAs, Palmtops, and Handy Terminals LED/Display Back Light Driver LEDs for Camera Flash Battery-Powered Equipment FEATURES ● Support up to 3 LEDs ● Low 50mV Dropout at 30mA ● Less than ±5% LED Current Matching ● Simple LED Brightness Control ● Low Shutdown Current ● 2.
