Description
Output enable, active low.
Circuit common.
Constant current output (sinking). Connect the cathodes of the LEDs to these pins.
Supply voltage. 6.5V to 90V. Bypass locally with a 100nF capacitor to ground.
The exposed underside plate is internally connected to the GND pin. The plate may either
be left floating or connected to ground. Solder the plate to an exposed copper area on the
PCB for heatsinking purposes (see recommended layout).
