The U479B-MFPY PMIC is designed to control lighting, ballasts and other lighting related components. The U479B-MFPY allows designers to optimize their power efficiency, dimming control, and light source lifetime while providing protection and long-term reliability.

The U479B-MFPY is a flexible and configurable integrated application PMIC specifically designed for lighting applications. It includes internal power supplies and rail management, as well as all the necessary drivers for dimmable and controllable lighting applications.

The device integrates multiple independent voltage regulators, active current sources, and gate drivers with a range of features designed to improve system cost, energy savings, EMI filtering, and longevity. These features include multiple power conversion topologies, multiple dimming control pathways, logic and analog voltage control, surge protection, and integrated switching power. All of these features can be configured and validated with the U479B-MFPY’s comprehensive set of system level programming and calibration capabilities.

The U479B-MFPY features a number of different operating modes that can be used to provide a wide range of control and dimming options. These include a dimmable analog signal, pulse width modulation (PWM) signal, and digital signal which support both constant current and constant voltage operation. The device can be used in applications such as LED drivers, digital ballasts, and AC/DC and DC/DC conversion. The U479B-MFPY provides integrated fault protection, surge and overvoltage protection, and EMI filtering for a comprehensive solution for lighting and ballast control applications.

The integrated system level programming and calibration capabilities enable the U479B-MFPY to automatically adjust power supply settings and load parameters, as well as to provide optimized dimming control performance. Furthermore, the high integration of the U479B-MFPY reduces design costs by eliminating the need for multiple external components, while providing system level features to improve the quality and accuracy of the dimming control presented to the user.
