UCC2305DWG4 Working Principle

The UCC2305DWG4 leverages advanced PWM technology for optimal dimming control and regulation of two power stages across the power supply’s input range and output range. The controller uses an internal, 10-bit digital-to-analog converter (DAC) to generate an output voltage to a 120Ω digital potentiometer on the ballast output stage for precise dimming control. The digital potentiometer adjusts the ballast output voltage to achieve the desired brightness.

Additionally, the UCC2305DWG4 employs a proprietary soft-switching technique to minimize the switching losses in the power stages, while minimizing audible noise and electromagnetic interference (EMF). The UCC2305DWG4 incorporates separate channels for each channel, providing better control of the power stages than conventional single channel control schemes. Moreover, the UCC2305DWG4 features an adjustable dimming rate that adjusts the dimming rate to perfectly match the dimming speed of the application, thereby reducing audible flickering.

Moreover, the UCC2305DWG4 includes a comprehensive, integrated protection suite for all of the critical functions in a dimmable lighting ballast circuit. Integrating these functions on a single chip enables developers to simplify their application designs, maintain data integrity and ensure system reliability.
