Hello Goutham, No, it was not intended for universal input. In general, analysis has shown that a universal dimming bulb design would prove more costly then two separate designs given the additional costs associated with the higher voltage design. But your case may prove otherwise, of course. The TPS92075 could be used for a low power factor, non-dimming, universal approach only. The ASNS pin is grounded and power factor functions are disabled, the device operates on a DC reference only, so PF is ~0.7 to ~0.8 depending on current and LED voltage.
Yes, you could consider:

The 92314 would have a smaller BOM, lower performance. The LM3447 would have a larger BOM but slightly higher performance.
