UCC3305DW is a high-performance electronic ballast controller suitable for dimming switch-mode power supplies in general lighting applications. It integrates an active current-sensing circuit, error amplifier, comparator, reference, thermal-protection circuit, digital-to-analog (DAC) converter, and other functions into a single integrated circuit. The integrated sensing and control circuitry makes the UCC3305DW a single-stage integrated solution for dimmable ballast applications, eliminating the need for an external controller.The UCC3305DW is optimized for maximum efficiency and power in lighting applications. It operates from a wide voltage range of 3.3 V to 30 V and can handle power levels up to 100 W. The device monitors the current through the ballast inductor and converts that current into a digital signal for precision control. The UCC3305DW also has a high switching frequency of up to 500 kHz, allowing for reduced component size and higher power density.The UCC3305DW features an active current-sensing circuit which provides precise control of the current through the ballast transformer. This allows precise control of the dimming level as well as low-frequency components in the power delivery waveform. The device also features a temperature compensation system, which accurately senses temperature changes and compensates the dimming level accordingly.The UCC3305DW also features an integrated comparator and reference voltage, allowing the user to set an output voltage for the LED ballast independently of the switch-mode power supply settings. This allows for precise control of the LED output voltage, increasing illuminance accuracy and efficiency.The UCC3305DW is suitable for dimming applications in general lighting, street lighting, and commercial lighting applications. The device integrates all the necessary circuitry for efficient and reliable dimming control, eliminating the need for an external controller. The device is ideal for use in applications where reliable, accurate dimming is required, such as in lighting control systems, HVAC systems, and industrial automation.In summary, UCC3305DW is a high-performance electronic ballast controller designed for dimming switch-mode power supplies in general lighting applications. The device features a wide voltage range, high switching frequency, integrated active current-sensing circuit, temperature compensation system, and integrated comparator and reference voltage, making it an ideal choice for efficient and reliable dimming control in commercial and industrial applications.
