Constant-Current Output
Constant-current value of each output channel is set by an external resistor connected between
the REXT pin and GND. Varying the resistor value can adjust the current scale ranging from 5mA to
90mA. The reference voltage of REXT terminal (Vrext) is approximately 1.2V. The output current
value is calculated roughly by the following equation:

In order to obtain a good performance of constant-current output, a suitable output voltage is
necessary. Users can get related information about the minimum output voltage above.
