TPS92210EVM-613 Datasheet PDF - TI

●TPS92210EVM-613 is a fully assembled and tested circuit for evaluating the TPS92210 natural PFC LED lighting driver controller. The controller uses cascode configuration which allows for faster start up times as well as eliminates the need for an external sense resistor for primary side current sense. Additionally, the controller employs a max on time modulation scheme that allows it to be used in a power factor correction circuit. This results in a compact LED driver design that achieves greater than 0.95 power factor driven by a single controller. The evaluation module is also compatible with a wide variety of TRIAC dimmers. Secondary side feedback responds to the conduction time of the sinusoidal wave, as governed by the TRIAC, and appropriately lowers the LED current to dim the LEDs. The secondary side also includes an adaptive supplemental load that sinks current when LED current becomes too low, therefore ensuring conduction of the TRIAC during very low dimming.
