SGM3123 Datasheet White Led Driver

Manufacturer: SG Micro

Overview: GENERAL.

General Description

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

It is optimized for low power keypad and portable backlighting applications.

The SGM3123 uses an internal resistor to set the bias current for four LEDs, which are matched to ±5%.

Key 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 in Green TQFN-3×3-16L Package.
