Note 2:
Note 3:
Enough current should be supplied into the VCC lead to keep the internal 15.6V zener clamp diode on this lead
regulating its voltage, VCLAMP.
The MAX lead is a voltage-controlled current source. For optimum dim interface current mirror performance,
this current should be kept between 0 and 750µA.
