Thank you Greenja for chiming in.
Madhuri,
We reviewed the design.
1.1A is desired vs the 1A at 12V it was intended for.
There will always be headroom already built into any design such as this.
Input is 36-75V of the PMP, so it can already do 1.1A, its just how much headroom is there at the low VIN?
The xfmr will be ok at 1.1A load. It looks like there is about a 10% margin on the the primary current limit at 1.1A load and 34V input.
So, it should be able to run at 1.1A load at 36V input. If it does hit current limit at 36V input, change the current limit resistor from 0.39 Ohms to 0.36 Ohms or 0.33 Ohms.
Thank you for using TI.
