SGM3127 White LED Driver

SGM3127 Description

SGM3127 White LED Driver with Low Dropout Current Source GENERAL .
The SGM3127 is a 4-channel white LED driver with integrated low dropout current sources.

SGM3127 Features

* Supply Voltage Range: 2.5V to 5.5V
* Support up to 4 LEDs
* Low 50mV Dropout Voltage at a 30mA Load
* Less than ±5% LED Current Matching
* Simple LED Brightness Control
* Less than 1μA Shutdown Current
* Thermal Shutdown Protection
* Operating Temperature Range: -40

SGM3127 Applications

* The SGM3127 integrates an internal resistor to set the LED bias current. It supports up to 30mA current per string. Compared with ballast resistors, the driver has many advantages such as lower dropout voltage, much lower bias variation with supply voltage variation and better efficiency The SGM312
