The KTA1140+KTB2140 Evaluation (EVAL) Kit is used to demonstrate and evaluate the KTA1140 and KTB2140 functionality, performance, and PCB layout. The kit includes a fully assembled and tested PCB with the KTA1140and KTB2140 IC installed. The KTA1140 device is an IEEE 802.3af/at/bt compliant power supply controller optimized for isolated and non-isolated converter topologies. Along with the KTB2140, this evaluation board utilizes 12V, 72W output with an active clamp forward topology. The KTA1140+KTB2140 evaluation board has power and signal I/O connections with an array of test points for signal observation.
