Functions and Advantages

CR-LED mode                                                                        The unique CR-LED mode developed by IT8900 series is especially applicable for LED driver test.The user only needs to set the operating voltage,current and coefficient of LED driver to obtain real output parameter of LED driver.Different from universal electronic load,this mode of IT8900 series adopts pure hardware circuit design without software operation by MCU module,thus increasing the speed and stability of CR mode control circuit,solving voltage and current jitter during LED  driver test,increasing frequency width and helping realize PWM dimming.
