Forum Post: TPS92510EVM Power up Failure

The documentation provides very little detail about bringing up the board. It says to connect the right LED load, apply  ~48VDC to the input, and it powers up at full output drive current. However, it isn't working that way. So I thought perhaps it needs to see a PWM input, so i provided that, at 700 kHz, and still there was no output. Perhaps there are some jumper settings that need to be made?  The documentation is not say either way.

In a nutshell, what is the fastest way to bring this board up?
