TPS92210: Questions for Natural PFC LED driver.

Part Number: TPS92210

Hello,

I would like ask a few questions about NATURAL PFC LED LIGHTING DRIVER CONTROLLER.

I need to drive 10-12 350mA power leds for a traffic light application so I want to know if this LED driver is good enough.

Firstly, I want a good Power factor over 95%, which is ensured according to datasheet.

Secondly,  very low no load power consumption. I did not read anything about it in the datasheet so I would like to ask is if I can achieve it with this led driver.

Also, I need fast turn-on and turn-off times with quick load discharge because I am going use this circuit with a 0.5Hz blinker.

Thank you very much.

ALEX

    Our EVM TPS92210EVM-647 for 120VAC input and TPS92210EVM-613 for 230VAC input are very close to your design specification. The user guide for both designs includes measured results. Based on what you provided it looks like TPS92210 will meet your requirements, but it's best if you order the board to measure and confirm.

    Best Regards,
