The KTA1137A Evaluation (EVAL) Kit is used to demonstrate the KTA1137A functionality, performance, and PCB layout. The KTA1137A is an IEEE 802.3af/at compliant combination powered device (PD) controller and power supply controller optimized for isolated and non-isolated converter topologies. The KTA1137A EVB demonstrates a 12V, 25W flyback converter for PD applications. The KTA1137A is pin compatible with the discontinued AS1138 and may be substituted with minimal effort.
