The KTA1142 is a single-chip, highly integrated CMOS solution for Power over Ethernet (PoE) Powered Devices with a PWM controller that integrates all the circuitry required to design a smart and efficient converter for PoE and telecom mid-power applications up to 71Watt output load, include Voice over IP (VoIP) Phones, and 5G/LTE Base Stations, Wireless LAN Access Point, Security Cameras, and Notebook computers.
The KTA1142 implements all the physical layer Powered Device (PD) functionality, as required by IEEE® 802.3af-2003 and IEEE® 802.3at-2009 and IEEE® 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.
