PWR_OK is an output, indicating that the supply is working like it 
should. You don't need to do anything here, though an LED, driven by a 
transistor may be useful for diagnostics: PWR_OK will be low when the 
supply is shutting down because of a short circuit, or because your load 
is too small. An LED without a transistor will not do, because PWR_OK is 
only guaranteed to source 200µA.
