This graph displays the measured output current versus CHG ISET DAC at an input voltage of 400 Vdc. A PWM signal is provided at J8 with a frequency of 100 kHz, an amplitude of 2.5 V, and a duty cycle varying between 0% and 100%. A constant resistance mode load of 200 Ω is used and V_OUT is allowed to vary with the current control.
