0 GENERAL DESCRIPTION The SP7121 LED driver provides a simple solution for a matched current source for any color common cathode LEDs.
The common 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.
At shutdown mode (EN pin is LOW), the supply current drops to .
04μA typical.
The SP7121 is available in a small footprint RoHS compliant, lead-free and green/halogen free 6-pin SOT23 packages.
