Kinetic Technology KTA1140 | Demoboard KTA1140EUAQ-WB-MCEV01
IEEE 802.3af/at/bt PoE PD and Flyback Controller (includes KTB2140 + KTA1170)
Overview
| Topology | LAN / POE |
| Input voltage | 48 V |
| Output 1 | 12 V / 4.17 A |
| IC revision | 1.2 |
Description
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.
