TPS92074 Description

The TPS92074 is a hybrid power factor controller (PFC) optimized for driving LED lighting solutions that do not require phase dimming patibility. The device monitors the converter rectified AC waveform using an internal, low-power, digital controller. The controller and DAC generate a synchronized triangular reference to regulate the output current.
