• Overview: The ICB2FL01GXUMA2 is a digital ballast controller integrated circuit with built-in protection circuit.
• Applications: The ICB2FL01GXUMA2 is designed for DC ballasts driven by HID lamps, such as low and medium pressure sodium lamps and mercury vapor lamps.
• Features: The ICB2FL01GXUMA2 features protection functions such as over-current protection, open-circuit protection and over-temperature protection, and user-friendly pre-set functions. It also enables an easy user interface, especially with those switches only. The products are divided into two types: single channel and dual channel.
• Working Principle: The ICB2FL01GXUMA2 provides two channels of isolated voltage and current control. This allows the user to control the lamp luminance independently in each channel. Through the power feed-forward circuit, the feedback information can be collected and the output current of the series resonance switch can be controlled by the PWM signal. It also introduces the idea of across-the-line soft start, which prevents the lamp from being immediately energized at the moment of power on. The over-current protection circuit helps to protect the lamp from the output current exceeding the rated value. Through the temperature feedback circuit, the temperature inside the device can be monitored. The temperature protection circuit takes care of the protection of the device from the excessive temperature.
• Conclusion: In conclusion, the ICB2FL01GXUMA2 is a digital ballast controller integrated circuit designed to be used in DC ballasts driven by HID lamps. It provides various protection functions, user-friendly pre-set functions, and two channels of isolation voltage and current control. Through the power feed-forward circuit, the feedback information can be collected, and the output current of the series resonance switch can be controlled by the PWM signal. The temperature protection circuit also takes care of the protection of the device from the excessive temperature.
