DM634 Constant-Current Output Constant-current value (Iout *1) of each output channel is set by an external resistor connected between the REXT pin and GND. The current scale ranging can be adjusted from 5mA to 70mA by varying the resistor value. User can input GBC value to increase Iout to 90mA. The reference voltage of REXT terminal (Vrext) is approximately 1.23V. The output current value is calculated by the following equation: Iout(mA) 5 10 20 30 40 50 60 70 M 41.13 39.35 36.78 35.09 33.75 32.53 31.35 30.09 Output Current as a Functiono Rext value 0 10 20 30 40 50 60 70 80 0 1 23 4 5 678 9 10 Rext(KΩ) Output Current as a Function of Output Voltage 0 10 20 30 40 50 60 70 80 0 0.5 1 1.5 2 2.5 3 Vout (V) 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. *1 Iout is typical current value setting under 100% PWM duty cycle and 95 D GBC Value.
