I have discovered a Chinese chip that produces pure sine waves for power inverters. I produce small inverters (typically up to 100watts) for emergency lighting applications and with new LED technology, anything less that a good sine wave, kids the lamp into thinking it is connected to a dimmer and does not produce full light output. I have tried a commercial pure sinewave inverter connected to a 12v battery and the LED lamps work correctly.

Has anyone experience of this chip type TDS2285 and has a data sheet and application note been produced in english.

I would be very pleased to hear from anyone.
Thank you in advance.

Have you contacted the manufacturer?

 

Not much of a datasheet but Google Translate gets this:

Good luck!

Thank you that is a good start. The manufacturers web site is rejecting emails, so I dont know whether there are several who make it. The fdata sheet seems to refer to Union Power but when searched on the net, it seems to be a completely different site to one I was expecting. A completely different product and company profile.

So does that mean that you cannot reliably identify the manufacturer?
