Datasheet SP7121-Exar.pdf

General Description

The SP7121 LED driver provides a simple solution for a matched current source for any color mon cathode LEDs.

The mon cathode connection allows the user to increase the LED power dissipation by having the cathodes heat sinked to the ground plane of the circuit board.

The SP7121 output current value is set by an external resistor.

Key Features

  • LED Driver for Common Cathode Parallel Connected LEDs.
  • Ultra Low Dropout Voltage of 300mV @ 25mA.
  • No EMI, no Switching Noise.
  • Integrated Current Matching.
  • PWM Brightness Control.
  • Enable/Shutdown Control.
  • Shu.
