T6311A - Constant-Current White LED Bias Supply

General Description

The T6311A low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs.

The T6311A uses a single resistor to set the bias current for four LEDs, which are matched to 0.3%.

Key Features

  • Low 200mV Dropout at 9mA.
  • Up to 150mA LED Bias Current.
  • 0.3% LED Current Matching www. DataSheet4U. com.
  • Simple LED Brightness Control.
  • Low 40uA Supply Current.
  • Low 0.05uA Shutdown Current.
  • 2.5V to 5.5V Supply Voltage Range.
  • SOP-8 and SOT23-6 Package.
  • Output channel : SOP-8 package for four channel SOT23-6 package for three channel.
