Hi Support,

Do you have any solution for the 90W LED driver for LED lamp?

Below is the specification:
1) 90-270Vac
2) Output voltage : 68V-72V
3) Output current : 1.2A
4) PF : > 0.90 (270Vac)
5) Efficiency : >= 90% (90Vac-270Vac)
6) Line regulation: +/- 1%
7) Load regulation : +/- 1%
8) Harmonic: < 20%

Thanks.

    We have the TPS61197 which might be useful for this application.  The input voltage range is 8V to 30V DC, so you would need to step down and rectify the AC voltage prior to applying to the TPS61197.  I think a 10:1 transformer might work for this range followed by a rectifier.
