The SP712X driver's family provides a simple solution for a matched current source for any color common cathode LED configuration. 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 SP7120 may drive two LEDs or one LED at twice the current with two channels connected in parallel. The SP7122 can drive three LEDs or one LED at three times the current. The factory preset current values are 15mA (version A), 20mA (version B), or 25mA (version C) per channel. In shutdown mode (EN pin is LOW), the supply current drops to 40nA typical. The SP712x drivers are available in a small footprint 6-pin SOT23-6 package.
