The KTA1142 implements all the physical layer Powered Device (PD) functionality, as required by IEEE\u00ae 802.3af-2003 and IEEE\u00ae 802.3at-2009 and IEEE\u00ae 802.3bt-2019 standards. This includes 8-event classification, Type 1-2 or 3-4 PSE detection indicator, PD detection, under-voltage lockout (UVLO), and Hot-Swap FET integration.<\/p>\n<p>The integrated DC\/DC controller features adjustable slope compensation, dual complementary low-side drivers with programmable dead time, programmable soft-start, soft-stop, and a programmable frequency dithering. The controller\u2019s main target is Flyback topology or Active Clamp Forward Converter for PoE.BT applications.<\/p>\n<p>The KTA1142 has been architected to address EM emission concerns in PoE applications. The chip implements many design features that minimize transmission of system common-mode noise onto the Unshielded Twisted Pair (UTP). The device is designed to provide safe, low-impedance discharge paths directly to the earth ground, resulting in superior reliability and circuit protection.<\/p>\n\t    <a
