Product Functions and Advantages
CR-LED ModeThe CR-LED mode of the IT8912E is specifically designed for testing LED driver power supplies. By simply setting the operating voltage, current, and coefficient of the LED driver, the true output parameters of the LED driver can be measured. The CR-LED mode uses a purely hardware circuit design to improve the speed and stability of the CR mode control loop, thereby solving the problem of voltage and current jitter in LED driver testing.
