High Power LED driver Circuit

[Jai_4_U]

Hello All,

I am developing a circuit of LED lights with LED Driver TPS92210.

My Project specifications are:

Input - 100V~245v AC

Output - 19.2V / 0.78A

Power in output for LED(6 LED's) - 15W

I am working on a circuit but I like if anyone will suggest me something regarding this circuit.

I did not find any LED Driver in multisim.Can you please help me to solve it?

Regards,

Jainam Shah.

You would probably be best off talking to a TI application engineer.  According to the spreadsheet here, the max input range cannot be greater than 1.615 times the min input.  You may be able to do something fancy with a pair of circuits and a range switch or TI may have a different product that will work with a wider range ..

Edit:  Oops...  Actually, that requirement is only imposed when you need to do TRIAC dimming.  Check out that design tool for a recommended layout with your specs.
