I am using the LNK626PG and I am seeing the voltage drop on the output around -30C. It is fine down to -20c. The voltage drops 30%. The data sheet only shows the temperature effects down to -15C. The data sheet says it is specified for -40C. Has anyone seen this before? It only happens at very light loads when the LNK626PG has low loss. As the load is increased and the losses in the LNK626PG increase, it heats up and the regulation comes back in spec.
