It provides superior levels of thermal protection and the highest efficiency levels. This power integrated circuit is commonly used in the lighting, ballast controllers and other related applications.

Application Field

U6433B-MFP is a highly reliable and robust power integrated circuit (PMIC), known for superior levels of thermal protection and the highest efficiency levels. It is used in numerous lighting and ballast controller applications, such as LED dimming control, LED lighting fixtures, LED T8 lamps and ballasts, LCD backlight dimming solutions, street lamps and tunnel lamps, industrial ballast, etc. Additionally, it can be used in other electronic equipment, such as refrigerators and air conditioners, as well as in digital products and power supplies.

Working Principle

U6433B-MFP is a power integrated circuit (PMIC). It operates in two types of modes. In the first mode, the device acts as an overvoltage protection solution, protecting the circuit from overvoltage which could cause damage and malfunctions. In the second mode, it acts as an integrated boost-driver, with high on-resistance and low output impedance, which results in an efficient voltage transformation from one level to another. The device also features a large number of parameters, such as input voltage, current, frequency, power, and temperature, which can be adjusted for each application. This makes it suitable for various types of lighting and ballast control applications.

U6433B-MFP works on the principle of a buck-boost converter. The voltage of the input power source is first reduced to the required level, and then boosted back up to the desired output voltage. The buck-boost converter is a current-mode device and can provide fast response time and low distortion. It also provides a low-power operation, low supply current, and low output impedance.

U6433B-MFP also features internal self-protection circuitry, which is designed to protect it from over-current and over-temperature conditions. It also comes with a wide range of current and temperature protection parameters, which provides protection from fault conditions. In addition, it has built-in current-limiting and fault protection circuitry, which ensures that the circuit is safe and reliable.
