KTA1137A Eval Kit – IEEE 802.3at PoE PD with Integrated DC-DC Controller

The KTA1137A is an IEEE 802.3af/at compliant combination powered device (PD) controller and power supply controller optimized for isolated and non-isolated flyback with opto-coupled feedback or with PSR, or Buck converter topologies. The KTA1137A EVB-001 demonstrates a 12V, 25W isolated flyback converter for PD applications. The KTA1137A is a pin compatible with the discontinued AS1138 and may be substituted with minimal effort.
