Other Parts Discussed in Thread: TPS92640

Hi,

Does TI has IC for Syncronous offline AC/DC LED driver?

I've found TPS92640/41 driver but as I understand from ABSOLUTE MAXIMUM RATINGS the voltage on the VIN, UDIM, SW pins shouldn't exceed 90V. Is it possible to find the way to use TPS92640/41 for 230VAC LED driver

Hi Oleksiy,

You may try the two stage architecture. First stage is AC to DC using a buck converter and second is DC to DC using TPS92640/41.

Best regards,

Victor

Hi Victor,

I understand your input, and for a moment there is no driver to realize one stage synchronous topology.
