SGM3123 White LED Driver

SGM3123 Description

GENERAL .
The SGM3123 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED de.

SGM3123 Features

* Support up to 4 LEDs
* Low 40mV Dropout at 20mA
* Less than ±5% LED Current Matching
* Simple LED Brightness Control
* Low Shutdown Current
* 2.5V to 5.0V Supply Voltage Range
* Thermal Shutdown Protection
* Operating Temperature Range: -40℃ to +85℃
* Available

SGM3123 Applications

* The SGM3123 uses an internal resistor to set the bias current for four LEDs, which are matched to ±5%. The SGM3123's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some applications, significantly improv
