The TPS92075 is a hybrid power factor controller PFC with a built-in phasedimming decoder. The device analyzes line cycles continuously using an internal,low-power, digital controller for shape and symmetry. The power converter stagegenerates an analog current reference and uses it to regulate the outputcurrent. The device uses control algorithms to manipulate the analog reference.These algorithms optimize dimmer compatibility, power factor and total harmonicdistortion THD. Using a constant off-time control, the solution achieves low component count,high efficiency and inherently provides variation in the switching frequency.This variation creates an emulated spread spectrum effect easing the convertersEMI signature and allowing a smaller input filter.The TPS92075 also includes standard features: current limit, overvoltageprotection, thermal shut-down, and VCC undervoltage lockout, all in packages
