Kinetic Technologies KTA1140 Evaluation Kit

Kinetic Technologies KTA1140 Evaluation Kit was designed to demonstrate the functionality, performance, and PCB layout of the KTA1140. The KTA1140 is an IEEE 802.3af/at/bt compliant power supply controller optimized for isolated and non-isolated converter topologies. The kit features a fully assembled and tested PCB with the KTA1140 IC installed.

The KTA1140 Evaluation Kit employs the KTB1095 12V, 50W flyback topology voltage regulator. The KTB1095 integrates a gate driver for a fully synchronous output rectifier and a built-in digital isolator that can supply up to 3000VRMS isolation. The Kinetic KTA1140 evaluation board has power and signal I/O connections with an array of test points for signal observation.
