KTA1136: IEEE 802.3af compliant PoE PD with Integrated DC-DC Controller and Power FET

San Jose, Calif. – August 17, 2021 – Power management and video/audio interface leader, Kinetic Technologies, is expanding its PoE power solutions portfolio with the introduction of KTA1136, a single-chip, highly integrated solution for 13W Power over Ethernet (PoE) Powered Devices (PD) significantly improving performance, while reducing both solution cost and size. Fully compliant with the IEEE® 803.2af specification, KTA1136 integrates input surge protection, a PD controller with 100V, 0.49Ω hot-swap MOSFET and a DC-DC controller with a robust 150V, 0.7Ω switching power MOSFET.

Senior Director of ESIA Marketing at Kinetic, Phil Dewsbury, says, “The integration of the 150V rated output MOSFET coupled with 600kHz switching frequency results in more than a 25% reduction in solution size, providing our customers with the smallest 13W PoE solution on the market today, making it ideal for space critical applications. Special care has been taken to minimize EMI and to optimize the light load efficiency without the switching frequency straying into the audio band”.

KTA1136 is fully compliant with IEEE 803.2af, but also supports IEEE, 803.2at and IEEE 802.3bt specifications for Type 1 power applications.

KTA1136 also includes PD Detection, classification and protection including under-voltage lockout (UVLO) and over-temperature protection (OVP).

Key applications for the new KTA1136 include Voice over IP (VoIP) Phones, Wireless LAN Access Point, Security Cameras, Biometric Authentication, Point-of-Sales Terminals, RFID Readers, Thin Clients and IoT Appliances.

KTA1136 is available and shipping now. Visit Kinetic Technologies for more information.
