Kinetic Technologie 13W Powered Device and DC-DC Controller Integrating a 150V Output MOSFET for Space-saving PoE Solutions
KTA1136: IEEE 802.3af Compliant PoE PD with Integrated DC-DC Controller and Power FET for Space-saving PoE Solutions(Space-saving PoE Solutions)
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 Phones(VoIP Phones), Wireless LAN Access Point, Security Cameras, Biometric Authentication, Point-of-Sales Terminals, RFID Readers, Thin Clients, and IoT Appliances.
